They named the breed "Suqutranese" since "White Somali" was unacceptable to registries. Fanny and three of her offspring 2 females and one male were shown at the CA of Great Britain show in March The Suqutranese standard is nearly identical to that of the Somali except the coat must be completely white with silver-white ticking and the nose-leather and paw-pads to be pink.

The breeders were hopeful that approval for the breed would be granted by the Cat Association of Great Britain. However, in August the Somali Cat Breed Advisory Committee took offence at advertisement in various publications for "so-called White Somalis" and issued a statement that Somalis are cats with ticked coats i. Any cat with a coat of only one colour is not a Somali and should not be described or sold as such.

Since the Suqutranese has a silvery ticked coat and has its own breed name White Somali being a descriptive term only , this seemed to be a breed society concerned about purity of coloured Somalis. Since then, nothing has been heard of the Suqutranese which is a great pity. A number of Somali breeders overseas have shown interest in re-creating the Suqutranese and it would make a glamourous new addition to the showbench.

It would also not be too difficult to reproduce the results under a less political cat registry by using a silver Somali male on suitable white females. In the early days of Abyssinian breeding, a solid black female called Nigra was produced and was bred fro. The fourth type of tabby is the spotted tabby. In some mackerel tabbies, the stripes have a natural tendency to break up to form bars or vertically aligned spots.

At first it was suggested that the spotted tabby was simply another mutation of the same gene which caused ticked, mackerel and classic tabby. Spotted tabbies were therefore "broken tabbies". In , more research was done and showed that a separate modifier gene is responsible for turning stripes into spots although the location of the gene hasn't been determined.

There are a number of spotted breeds in existence. The oldest recognised is probably the Spotted British Shorthair. British Shorthairs have been recognised since the s while American Shorthairs have been recognised as "Domestic Shorthairs" since the s. The Egyptian Mau may be older, but was not recognised as a breed until the s. The British and American Shorthairs and the Egyptian Mau are naturally occurring breeds which have been refined by selective breeding. The Egyptian Mau is sometimes claimed to be the oldest or only naturally occurring spotted breed.

This, however, overlooks the Bahraini Dilmun Cat, a spotted variety which is barely known in its own country, let alone internationally. It is also in danger of being lost due to breeding with abandoned Persian cats in Bahrain Persians ar popular pets, but once the novelty wears off they are frequently turned out to fend for themselves.

Dilmun cats are semi-foreign in conformation and have evolved to survive in Bahrain's extremely high summer temperature. Only recently has there been any interest in maintaining this as a breed. The Ocicat and was derived from crossing Siamese with Abyssinian cats to create a ticked-point Siamese.

The ocelot-like spotted cat was an attractive surprise result. The addition of domestic tabby shorthairs refined the type and the pattern and some Spotted Mists show a tendency to a rosetted pattern. The California Spangled Cat was an early "designer breed" bred in the s to resemble spotted wild cats, but without hybridisation with wild species. The body is spotted and lower legs are striped. A "King Spangled" version had marbled markings like a King Cheetah.

These cats never achieved the popularity of the Bengal or Ocicat. The breed had a high profile launch in the s and though still listed by TICA it has almost disappeared. The Kanaani Canaan Cat being developed in Germany is being bred to resemble the spotted wildcat subspecies Felis lybica gordonii, but with domestic temperament. Early photographs suggest an Oriental-type or Ocicat-type spotted breed. Those were the "first four" of the non-hybrid spotted cats - Spotted Shorthair, Egyptian Mau, Ocicat, Australian Mist six non-hybrid spotted breeds when the Bahraini Dilmun and Kanaani are counted.

There are also spotted breeds where the pattern has been inherited from a wild species of small cat which has been interbred with domestic cats. The Ussuri is a natural breed of from along the Amur river, Russia. It has reputedly crossed with small wild cats in the area - "Amur Forest Cats" or "Amur Leopard Cats" Asian Leopard cat subspecies which may make it a hybrid breed. It is a more robust variety which occurs semi-wild and has also interbred with semi-wild cats of Siberian and domestic shorthair type.

The pattern is said to be distinctive - vertical solid or merged spots, which may have been inherited from the wildcat. Whether it is a hybrid is not proven. A superbly rosetted Cashmere semi-longhaired equivalent of the Bengal. Photo courtesy Corine Kooy, Cashmere Cattery. In the Bengal was developed from crossing domestic cats with the spotted Asian Leopard Cat. The original intent was to study the Asian Leopard Cat's supposed natural immunity to certain feline diseases and whether this could be transferred to domestic cats.

The end result has been an attractive spotted breed that also includes some margay genes from the Bristol breed developed and abandoned around the same time the Bristol cats are believed to have introduced the best rosette patterns. In the s, the Geoffroy's Cat was crossed with domestic cats in order to produce the Safari breed with the wild-type rosetted pattern seen in big cats such as leopards and jaguars.

Since then. Domestic cats have been deliberately crossed with jungle cats Chausie , servals Savannah, Ashera and fishing cats Viverral, Machbagral in attempts to create wild-looking spotted breeds of domestic cat. Punjabis are large, elegant cats resembling the wild parent. The colours are grey-black low contrast spots on ticked ivory to chocolate spots on ticked sandy colour. The spots are randomly aligned and low contrast like the wild parent.

The marbled or clouded pattern is thought to be a variation of the classic tabby pattern. It's a term given to the horizontally aligned swirling of the tabby pattern in certain breeds. The centre of the dark markings contain areas of agouti i. Marbled also occurs in a different form in the Bengal above through the interaction of wild-type spotting from the Leopard Cat ancestor and domestic-type classic tabby.

The marbled tabby pattern is occasionally been seen in cats with no known Bengal or other wild-type ancestry. Other breeds have chosen different terms for this pattern - in the Highland Lynx breed, the marbled tabby pattern is known as "clouded leopard". The Sokoke is a natural breed found in the Sokoke Forest area of Kenya. It is now being developed in Denmark. The pattern of the Sokoke is a modified form of classic tabby peculiar to that breed.

Agouti ticked hairs appear in the centre of the blotched markings to create "hollow" tabby markings. Indian street cat Serval pelts. While the distinct spots found on Egyptian Mau, Ocicat and several other breeds are due to a spotted modifier gene acting on mackerel tabby, there is evidently more to learn about spotted patterns in cats.

For example this India street cat submitted by Vasilis Lekka shows a distinct "freckled pattern" of very small spots. A small spot pattern is also showing up in some Savannah cats and may be due to a gene found in the Serval species one of the parent species of the Savannah breed which produces the "Servaline" pattern.

The Poljun also includes the servaline pattern. No doubt there is much more to be discovered about the striped, spotted and marbled patterns with the introduction of genes from the African serval, the Jungle cat, Geoffroy's Cat and the Fishing Cat into the genetic melting pot. These are all colloquial tems rather than cat fancy terms.

These are variations on the tabby theme that can be seen in random-bred populations. Pastel tabby is a colloquial term for blue cream tortie tabbies where the tabby pattern is overlaid on a brindled tortoiseshell the blue and cream hairs are intermixed giving a hazy effect as shown below.

Viewed closely, the pattern colour is heavily ticked on a paler ticked background. This breakthrough pattern is evident from kittenhood and not the same as age-related darkening in Colourpoint cats. A similar effected of dark ticked markings on pale ticked bckground is found in the Australian Mist breed. A stongly marked seal-tabby Siamese with a breakthrough spotted pattern looked like a Spotted Tabby Oriental with blue eyes mated to a Siamese produced a litter containing one strongly marked classic tabby that looked more like a Classic Tabby Oriental with blue eyes.

The breakthrough pattern has become a problem in some Australian lines. Another example was a lynx-point Siamese female old-style conformation in England that looked like a slightly washed out tabby with blue eyes. Her colour raised questions as to whether she was genuinely colourpoint or was genetically mink or sepia pattern from Tonkinese lines.

The Inhibitor gene is more effective at blocking black-based pigment than blocking red-based pigment, hence there may be a breakthrough of reddish colour known as "tarnishing". Tarnishing is common on the muzzles of random bred silver tabbies, but rare on pedigree silver tabbies due to selective breeding and refinement. Amber is a colour peculiar to Norwegian Forest Cats caused by a black modifier gene.

It was discovered during the s and initially thought to be due to the genes for chocolate, lilac, cinnamon or fawn; these genes are not permissible in the breed as they indicate outcrossing to other breeds. Some cats were registered as goldens. Testing matings with chocolate point Birmans and between the so-called "x-colour" cats demonstrated it to be a new colour due to a black modifier gene.

The two new colours are called Amber and Light Amber; amber is a modifed form of black and light amber is a modified form of blue. Their original birth colour is often seen only on the back and tail, allowing amber and light amber to be distinguished from one another. Amber is apricot-to-cinnamon colour with brown paw pads, nose leather and eye rims.

Kittens are born dark or black, with ghost markings resembling poor quality silver tabbies , and brighten as they mature. Light Amber is a pale beige colour. Kittens are born blue and brighten with age, becoming pink-beige to fawn at maturity. The nose leather, eye rims and paw pads are dark blue grey. The nose is pink and the paw pads and eye rims are brown. The nose is pink and the eye rims and paw pads are blue-grey.

Silver tabby is caused by the presence of the dominant Inhibitor gene. Silver tabbies have a silvery background colour with a tabby pattern overlaid on it. Silver tabbies in the random breeding population are prone to tarnishing - the appearance of a yellowish or rusty hue.

The Inhibitor gene seems eliminate the yellow pigment in the ticked hairs of the background colour, but does not affect the solid coloured areas the markings. The best known silver tabbies are those with black markings as shown on this page. Silver tabbies with other colour markings also occur e. The Inhibitor gene has also been introduced into Abyssinians and Somalis to create silver-undercoated varieties of ticked tabby.

The Golden Tabbies have a brighter more golden background colour gained from inheriting the recessive form of the Inhibitor gene from Chinchilla parents. The Inhibitor gene causes silver tabbies, but since most genes occur in pairs the Inhibitor gene has a partner gene, sometimes referred to as "non-Inhibitor". It has been suggested that the brighter background colour of Golden tabbies is due to a "Wide Band" gene which determine the width of the hair shaft colour between the pigmented tip and the follicle.

Golden Shadeds lack the dominant Inhibitor gene, but have a shading pattern comparable to Silver Shaded cats. It's likely that there are polygenes that affect the undercoat width. In September researchers announced they had identified the gene that switches between mackerel and classic tabby patterns. This is the first "pattern gene" to be identified. In inheritance terms, mackerel pattern is the dominant "wild type" gene while classic pattern is due to a recessive gene.

Cats with narrow stripes mackerel tabby have a working copy of the gene. The blotched pattern classic tabby occurs when a mutation turns that gene off. The researchers noted that cells in the black stripes or spots in the case of cheetahs know they are in a black stripe and remember that fact throughout the animal's life so that the pattern grows as the cat grows.

They analysed DNA samples from feral cats in northern California and the DNA of cheetahs, including samples from the blotched "king cheetah" a recessively inherited "classic tabby" version of the cheetah. The research pointed to a gene they called Taqpep Transmembrane aminopeptidase Q.

Blotched house cats had mutations in this gene, while striped tabbies did not. The king cheetah also had a Taqpep mutation while the spotted cheetah had a normal version of the gene. The Taqpep gene produces an enzyme that diffuses outside of cells, interacting with other molecules. Another gene, called Edn3 Endothelin3 , led to the growth of dark fur rather than light fur and coordinated localized colour differences.

Together, Taqpep and Edn3 produced the patterning: Taqpep establishes the type of pattern of stripes or spots in early development while Edn3 appeared to carry this on during growth. Other genes, not yet identified, would determine further variations in the basic tabby patterns in domestic cats, for example broken stripes, round spots, marbled tabby Bengal or pale-centred blotches Sokoke. Kaelin, Kelly A. Barsh in Nature Communications volume 12, Article number: The researchers analysed cells from foetal skin of domestic cats to identify when, where, and how tabby patterns are established during foetal development.

The foetuses were obtained from pregnant feral cats spayed during Trap-Neuter-Return programmes. In mammalian skin and hair, melanocytes are uniformly distributed during development, and the amount and type of melanin produced are controlled later by paracrine signalling molecules within individual hair follicles.

Paracrine signalling is a form of cellular communication in which a cell produces a signal to induce changes in nearby cells. Step 1: Pattern element is set during foetal development. Step 2: Pattern is implemented by paracrine signalling molecules produced within individual hair follicles e. This means individual spots or stripes present at birth enlarge proportionally as the infant grows. In previous studies of domestic cats, the same researchers showed that Endothelin 3 is expressed at the base of hair follicles in tabby markings.

More black-brown eumelanin is produced relative to reddish-yellow pheomelanin. This plays a key role in producing the tabby markings. Tabby markings are apparent in developing hair follicles before they produce hair i. At stage 13 analogous to mouse embryonic day 11 , foetal skin is a uniform layer of epithelial surface cells, one cell thick, over a dermis that contains few cells.

By stage 22 analogous to mouse post-natal day 4—6 , there are well-developed hair follicles that can be categorized according to the type of melanin they produce. Dark markings contain mostly eumelanin, while light areas contain mostly phaeomelanin. The researchers looked at natural genetic variation in Transmembrane aminopeptidase Q, Taqpep enzyme. Loss-of-function mutations in Taqpep cause the striped mackerel tabby pattern to expand into the blotched classic tabby.

Both patterns are found in feral cat populations. The thick epidermal regions of mackerel tabby embryos were organized into vertically oriented columns separated by larger thin epidermal regions. In classic tabby embryos, the thick epidermal regions in the flank and back of the neck are broadened.

The alternating thick and thin regions arise from an earlier molecular pre-pattern. The researchers looked at two Dkk4 variants called p. Ala18Val and p. Cys63Tyr that were only found in breeds where tabby markings were obscured: Abyssinian, Burmese and Siamese. Ala18Val or p. Cys63Tyr Dkk4 variants, most being homozygotes, some being heterozygotes for the variants.

In some breeds Oriental Longhair, Oriental Shorthair and in non-breed cats, which had either Ticked or non-Ticked phenotypes, these patterns correlated with the presence or absence of the p. Ala18Val Dkk4 variant. A feral foetal skin sample heterozygous for p. In domestic cats, the servaline pattern is one of several examples demonstrating that the effect of Dkk4 depends on genetic background and genetic interactions.

However, in the Burmese breed, individual hairs are not banded due to a loss-of-function Agouti allele and Ticked has been selected for its ability to suppress tabby markings.

Early on when pattern inheritance was studied, it was believed that three alleles gene variants at the same locus position on a chromosome controlled the tabby pattern. Different pairings of these genes produced the following order of dominance in tabby patterns: ticked Abyssinian Ta , Spotted Ts , Mackerel TM , and Blotched Classic tb.

Two copies of ticked completely masked the tabby pattern, one copy of ticked and one of non-ticked allowed stripes to show up on the extremeties while 2 copies of non-ticked allowed the tabby pattern to show through. Some other mechanism seemed to break up stripes into spots. Three independent breeding lines in controlled environments were used:. Eizirik, E, VA David et al's paper proposed the symbol Ta with alleles TaM mackerel, dominant and tab blotched, recessive for the pattern-type locus; TiA Abyssinian ticked and Ti1 non-ticked for the other locus which can fully or partly mask the pattern.

A name was not posted for the spotted modifier locus though Straede has previously posited Pmf" breaks the pattern into spots and recessive "pmu" leaves the pattern unbroken. Self indicates a solid colour. Agouti is not included. The oceloid pattern is intriguing as it suggests rosetting or clouding, a pattern only recently introduced into cats via hybridization with wild species. Genes for creating or modifying spotted patterns have been introduced into the domestic cat from wild species.

The Bengal breed derived from hybrids with the Asian Leopard Cat exhibits a more random type of spotting as well as the coveted rosette pattern groups of spots and a swirled marble pattern where domestic cat tabby and wild type spotting interact. The inclusion of the Bristol breed a margay hybrid into some Bengal lines may have added other genes for spots.

The Celonese is a small ticked tabby which originated in Sri Lanka and is now being bred in Italy. A slightly different form of ticking is found in the Chausie, a breed derived from hybridising F chaus Jungle Cat with the domestic cat. Although superficially solid white, the Suqutranese Socotranese is essentially a ticked cat. It is a Somali-type semi longhair with white fur with glistening silver banding.

UK registries and Somali breed societies frown upon anyone advertising "White Somalis" so the Suqutranese is not well known. Somali societies distance themselves from the breed. Socotra off the coast of Somalia where they noticed a pure white cat with the conformation and temperament of a Somali. Its white fur had well-defined bands of silvery white clearly visible on the individual hairs.

Ms Garrard had a pedigree usual silver Somali male Clyde and two white shorthair females. First generation kittens were a mixture of Somali colours and pure whites, mostly semi-longhairs of Somali type. In , Fanny was mated back to her father, producing five White Somali kittens. Ms Garrard and the Barretts set up a breeding programme to seek recognition for white semi-longhairs of Somali type.

They named the breed "Suqutranese" since "White Somali" was unacceptable to registries. Fanny and three of her offspring 2 females and one male were shown at the CA of Great Britain show in March The Suqutranese standard is nearly identical to that of the Somali except the coat must be completely white with silver-white ticking and the nose-leather and paw-pads to be pink.

It would also not be too difficult to reproduce the results under a less political cat registry by using a silver Somali male on suitable white females. In the early days of Abyssinian breeding, a solid black female called Nigra was produced and was bred fro.

The fourth type of tabby is the spotted tabby. In some mackerel tabbies, the stripes have a natural tendency to break up to form bars or vertically aligned spots.

There are a number of spotted breeds in existence. The oldest recognised is probably the Spotted British Shorthair. British Shorthairs have been recognised since the s while American Shorthairs have been recognised as "Domestic Shorthairs" since the s.

The Egyptian Mau may be older, but was not recognised as a breed until the s. The British and American Shorthairs and the Egyptian Mau are naturally occurring breeds which have been refined by selective breeding. The Egyptian Mau is sometimes claimed to be the oldest or only naturally occurring spotted breed.

This, however, overlooks the Bahraini Dilmun Cat, a spotted variety which is barely known in its own country, let alone internationally. It is also in danger of being lost due to breeding with abandoned Persian cats in Bahrain Persians ar popular pets, but once the novelty wears off they are frequently turned out to fend for themselves. Dilmun cats are semi-foreign in conformation and have evolved to survive in Bahrain's extremely high summer temperature.

Only recently has there been any interest in maintaining this as a breed. The Ocicat and was derived from crossing Siamese with Abyssinian cats to create a ticked-point Siamese.

Domestic cats have been deliberately crossed with jungle cats Chausie , servals Savannah, Ashera and fishing cats Viverral, Machbagral in attempts to create wild-looking spotted breeds of domestic cat.

Punjabis are large, elegant cats resembling the wild parent. The colours are grey-black low contrast spots on ticked ivory to chocolate spots on ticked sandy colour. The spots are randomly aligned and low contrast like the wild parent. The marbled or clouded pattern is thought to be a variation of the classic tabby pattern. It's a term given to the horizontally aligned swirling of the tabby pattern in certain breeds.

The Sokoke is a natural breed found in the Sokoke Forest area of Kenya. It is now being developed in Denmark. The pattern of the Sokoke is a modified form of classic tabby peculiar to that breed. Agouti ticked hairs appear in the centre of the blotched markings to create "hollow" tabby markings. Indian street cat Serval pelts. While the distinct spots found on Egyptian Mau, Ocicat and several other breeds are due to a spotted modifier gene acting on mackerel tabby, there is evidently more to learn about spotted patterns in cats.

For example this India street cat submitted by Vasilis Lekka shows a distinct "freckled pattern" of very small spots. A small spot pattern is also showing up in some Savannah cats and may be due to a gene found in the Serval species one of the parent species of the Savannah breed which produces the "Servaline" pattern. The Poljun also includes the servaline pattern.

No doubt there is much more to be discovered about the striped, spotted and marbled patterns with the introduction of genes from the African serval, the Jungle cat, Geoffroy's Cat and the Fishing Cat into the genetic melting pot. These are all colloquial tems rather than cat fancy terms. These are variations on the tabby theme that can be seen in random-bred populations.

Pastel tabby is a colloquial term for blue cream tortie tabbies where the tabby pattern is overlaid on a brindled tortoiseshell the blue and cream hairs are intermixed giving a hazy effect as shown below. Viewed closely, the pattern colour is heavily ticked on a paler ticked background.

This breakthrough pattern is evident from kittenhood and not the same as age-related darkening in Colourpoint cats. A similar effected of dark ticked markings on pale ticked bckground is found in the Australian Mist breed.

A stongly marked seal-tabby Siamese with a breakthrough spotted pattern looked like a Spotted Tabby Oriental with blue eyes mated to a Siamese produced a litter containing one strongly marked classic tabby that looked more like a Classic Tabby Oriental with blue eyes. The breakthrough pattern has become a problem in some Australian lines.

Another example was a lynx-point Siamese female old-style conformation in England that looked like a slightly washed out tabby with blue eyes. Her colour raised questions as to whether she was genuinely colourpoint or was genetically mink or sepia pattern from Tonkinese lines.

The Inhibitor gene is more effective at blocking black-based pigment than blocking red-based pigment, hence there may be a breakthrough of reddish colour known as "tarnishing". Tarnishing is common on the muzzles of random bred silver tabbies, but rare on pedigree silver tabbies due to selective breeding and refinement. Amber is a colour peculiar to Norwegian Forest Cats caused by a black modifier gene.

It was discovered during the s and initially thought to be due to the genes for chocolate, lilac, cinnamon or fawn; these genes are not permissible in the breed as they indicate outcrossing to other breeds. Some cats were registered as goldens. Testing matings with chocolate point Birmans and between the so-called "x-colour" cats demonstrated it to be a new colour due to a black modifier gene. The two new colours are called Amber and Light Amber; amber is a modifed form of black and light amber is a modified form of blue.

Their original birth colour is often seen only on the back and tail, allowing amber and light amber to be distinguished from one another. Amber is apricot-to-cinnamon colour with brown paw pads, nose leather and eye rims. Kittens are born dark or black, with ghost markings resembling poor quality silver tabbies , and brighten as they mature. Light Amber is a pale beige colour.

Kittens are born blue and brighten with age, becoming pink-beige to fawn at maturity. The nose leather, eye rims and paw pads are dark blue grey. The nose is pink and the paw pads and eye rims are brown. The nose is pink and the eye rims and paw pads are blue-grey. Silver tabby is caused by the presence of the dominant Inhibitor gene. Silver tabbies have a silvery background colour with a tabby pattern overlaid on it.

Silver tabbies in the random breeding population are prone to tarnishing - the appearance of a yellowish or rusty hue. The Inhibitor gene seems eliminate the yellow pigment in the ticked hairs of the background colour, but does not affect the solid coloured areas the markings. The best known silver tabbies are those with black markings as shown on this page.

Silver tabbies with other colour markings also occur e. The Inhibitor gene has also been introduced into Abyssinians and Somalis to create silver-undercoated varieties of ticked tabby. The Golden Tabbies have a brighter more golden background colour gained from inheriting the recessive form of the Inhibitor gene from Chinchilla parents.

The Inhibitor gene causes silver tabbies, but since most genes occur in pairs the Inhibitor gene has a partner gene, sometimes referred to as "non-Inhibitor". It has been suggested that the brighter background colour of Golden tabbies is due to a "Wide Band" gene which determine the width of the hair shaft colour between the pigmented tip and the follicle. Golden Shadeds lack the dominant Inhibitor gene, but have a shading pattern comparable to Silver Shaded cats.

It's likely that there are polygenes that affect the undercoat width. In September researchers announced they had identified the gene that switches between mackerel and classic tabby patterns. This is the first "pattern gene" to be identified.

In inheritance terms, mackerel pattern is the dominant "wild type" gene while classic pattern is due to a recessive gene. Cats with narrow stripes mackerel tabby have a working copy of the gene. The blotched pattern classic tabby occurs when a mutation turns that gene off.

The researchers noted that cells in the black stripes or spots in the case of cheetahs know they are in a black stripe and remember that fact throughout the animal's life so that the pattern grows as the cat grows. They analysed DNA samples from feral cats in northern California and the DNA of cheetahs, including samples from the blotched "king cheetah" a recessively inherited "classic tabby" version of the cheetah.

The research pointed to a gene they called Taqpep Transmembrane aminopeptidase Q. Blotched house cats had mutations in this gene, while striped tabbies did not. The king cheetah also had a Taqpep mutation while the spotted cheetah had a normal version of the gene.

The Taqpep gene produces an enzyme that diffuses outside of cells, interacting with other molecules. Another gene, called Edn3 Endothelin3 , led to the growth of dark fur rather than light fur and coordinated localized colour differences. Together, Taqpep and Edn3 produced the patterning: Taqpep establishes the type of pattern of stripes or spots in early development while Edn3 appeared to carry this on during growth.

Other genes, not yet identified, would determine further variations in the basic tabby patterns in domestic cats, for example broken stripes, round spots, marbled tabby Bengal or pale-centred blotches Sokoke. Kaelin, Kelly A. Barsh in Nature Communications volume 12, Article number: The researchers analysed cells from foetal skin of domestic cats to identify when, where, and how tabby patterns are established during foetal development.

Step 1: Pattern element is set during foetal development. Step 2: Pattern is implemented by paracrine signalling molecules produced within individual hair follicles e. This means individual spots or stripes present at birth enlarge proportionally as the infant grows.

In previous studies of domestic cats, the same researchers showed that Endothelin 3 is expressed at the base of hair follicles in tabby markings. More black-brown eumelanin is produced relative to reddish-yellow pheomelanin.

This plays a key role in producing the tabby markings. Tabby markings are apparent in developing hair follicles before they produce hair i. At stage 13 analogous to mouse embryonic day 11 , foetal skin is a uniform layer of epithelial surface cells, one cell thick, over a dermis that contains few cells. By stage 22 analogous to mouse post-natal day 4—6 , there are well-developed hair follicles that can be categorized according to the type of melanin they produce.

Dark markings contain mostly eumelanin, while light areas contain mostly phaeomelanin. The researchers looked at natural genetic variation in Transmembrane aminopeptidase Q, Taqpep enzyme. Loss-of-function mutations in Taqpep cause the striped mackerel tabby pattern to expand into the blotched classic tabby. Both patterns are found in feral cat populations. The thick epidermal regions of mackerel tabby embryos were organized into vertically oriented columns separated by larger thin epidermal regions.

In classic tabby embryos, the thick epidermal regions in the flank and back of the neck are broadened. The alternating thick and thin regions arise from an earlier molecular pre-pattern. The researchers looked at two Dkk4 variants called p. Ala18Val and p. Cys63Tyr that were only found in breeds where tabby markings were obscured: Abyssinian, Burmese and Siamese.

Ala18Val or p. Cys63Tyr Dkk4 variants, most being homozygotes, some being heterozygotes for the variants. In some breeds Oriental Longhair, Oriental Shorthair and in non-breed cats, which had either Ticked or non-Ticked phenotypes, these patterns correlated with the presence or absence of the p.

Ala18Val Dkk4 variant. A feral foetal skin sample heterozygous for p. In domestic cats, the servaline pattern is one of several examples demonstrating that the effect of Dkk4 depends on genetic background and genetic interactions. However, in the Burmese breed, individual hairs are not banded due to a loss-of-function Agouti allele and Ticked has been selected for its ability to suppress tabby markings.

The Tabby cat locus maps to feline chromosome B1. Early on when pattern inheritance was studied, it was believed that three alleles gene variants at the same locus position on a chromosome controlled the tabby pattern.

All four of the tabby patterns share several characteristics that distinguish tabbies from other patterns. There is also a cream spotted tabby color, however we were unable to find an image. I have a photo of a spotted tabby that you do not show.

I had a true cream, but he was already adopted and for whatever reason, none of the baby pictures I have of him are at an angle to really show his spots. If you tell me how, I would be happy to provide you with a picture of a true orange spotted tabby. I have a picture of a cream tabby that I would like to share. It is not the most regal picture but it shows his spots that identify him as a cream tabby. If you would like this photo added to your collection please email me at: UniversalStar yahoo.
