Cat fur color is a common teaching tool in biology and genetics classes.  A normal (dominant) Agouti gene allows cat hairs to be banded yellow and black, and thus allows Tabby genes to be expressed (lots of fun, see below).  A recessive mutation at Agouti is responsible for black cats, called “seal” is some breeds such as the Siamese. The Brown gene (Locus B) in the cat affects the intensity of black pigment. White markings are a prominent feature of cat colour genetics.  Interestingly, white is not a colour per se, but is rather a lack of colour.  In fact, white results from a developmental lack of cells (called melanocytes) that produce pigmentation. The Agouti gene, found at Locus A is the master gene for yellow pigment production.  In the cat, the Agouti gene is either active, allowing yellow pigment to be formed, or not active, which eliminates yellow pigment formation but still allows black pigment to be produced. The Spot Tabby locus is responsible for spots of black pigment on a yellow pigment background.  Think of little leopards.  Spots are seen in traditional cat breeds such as the Ocicat and in hybrid breeds such as the Bengal.  The genetics of Spot are not well understood. Colorpoint refers to the fact that ears, paws and tails of the cat are more darkly pigmented compared to the body.  This is the key component of coloration in several breeds including Siamese and Burmese, and can give colorpoint variations such as Tonkinese.  There is an order of dominance of these variations (mutations) as follows: Other animals such as rabbits also have colorpoint mutations in their Locus C genes.  Dogs do not. Genetic testing allows breeders to predict the possible outcome of an upcoming litter and can prevent diseases to become an integral part of a breed. Cat Colors FAQ: Cat Color Genetics. These cats are at a higher risk from congenital deafness and skin cancer. Paw Print Genetics offers testing for common coat colors and traits. Dilution (blue and isabella) The D series. The effect of polygenes is cumulative on coat color genetics. In the Ticked Tabby pattern, an alternation of yellow and black pigment occurs within the hair shaft itself giving the cat a stylish ‘salt and pepper’ sheen to its coat as seen in Abyssinian cats.  Ticked is dominant over non ticked. Summary of series List of alleles for reference. Photography by Casey Elise Photography. A short video explaining some of the genetics of cat coat colour.  Quite frankly the Agouti gene is more interesting in dogs as it gives dominant yellow as well as black and tan colorations not seen in cats (see Dog Genetics 2.0: Colours).  Although we have the Agouti gene within our genome, it is not involved in the colour traits of hair in people.  Pity. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. Basic Feline Genetics.

The agouti gene is what determines whether each hair will be a solid color, or will be a gradient from one color to another. The genetics of short hair and long hair is relatively straight forward.  Short hair is the dominant copy (L) while long hair is the recessive copy (l/l) of the responsible gene.

Feline Coat Color Introduction The modern-day domestic cat displays a wide variety of coat colors and patterns. kitten generator . For a visual representation of colour genetics covered in this article, see the colour chart Cat Genetics 2.1: Colours Chart. This is a pattern in which the cat has a solid base color, but the bottom eighth of each hair is white or creamy.  Brown is a recessive trait that will modify the normal black pigment (B) to a brown colour (b/b) or to a cinnamon colour (b’/b’).  Normal coloration is dominant over brown, which in turn is dominant over cinnamon. Van (Red Mackeral Tabby Van) Mostly white, color mainly on head and tail. Bicolor (Black and White Bicolor) ~1/2 white, color on head and torso. Fever coat is an effect known in domestic cats, where a pregnant female cat has a fever or is stressed, causing her unborn kittens' fur to develop a silver-type color (silver-grey, cream, or reddish) rather than what the kitten's genetics would normally cause. There are a number of genes that contribute to the colour and the pattern of colour seen in the cat; these genes can be grouped into four levels of function: 1.  The good news is that the basics of colour genetics in the cat are relatively simple.  The not so good news is that simplicity plus simplicity plus simplicity….will pretty quickly give us complexity. The rest of the color genes are actually patterns that affect the black or red. Tabby coat pattern in cats. Fortunately, the mapping of the feline genome allowed the genes that control coat, color and pattern in cats, to be studied and identified with DNA tests. There is a gene called Dilute-Modifier in the cat that in the presence of d/d will cause a further washing out of pigment colours.  Locus B (Brown) now gives ‘Carmel’ shades of colours while Locus O (Orange) gives Apricot.  The Dilute-Modifier gene is not as yet cloned or characterized. Cat Colors FAQ: Cat Color Genetics. cat coat calculator (original ver.)  Dominant White as it’s name indicates is dominant in that only one copy of the mutated gene (W) is needed to give the trait. Dilution is another gene that modifies the normal colours and will wash out or dilute both black pigment and yellow pigment.  Dilution is a recessive trait that will modify normal black pigmentation to give a grey colour (d/d) often called Blue.  Dilution can combine with B locus Brown (b/b) to give Lilac (Lavender) coat colour and with B locus Cinnamon (b’b’) to give Sable (Fawn) coat colour. Cat Color Genetics White. Cat coat genetics: Lenght and texture. Although they are not shown on the chart, Tortoiseshell cats can also have tabby patterns. Basic Feline Genetics. Cat eye color is due to the presence of melanin, which itself is the result of genetics. Pointed Color Chart. The colour modifying genes do not make the colour pigments, but they do influence the shade of the colour, usually by reducing its intensity i.e. The C Locus involves a master gene for pigment formation.  When the gene is active, both black and yellow pigments can be formed.  When the gene is mutated and not active, no pigment is formed.  A recessive mutation at the C Locus will give a white (albino) cat, but this is not something that is desirable for cat breeders.  However, cats have a very interesting series of additional mutations at the C Locus that give the Colorpoint traits. Colour is produced by special chemicals called pigment.  Pigment is produced in special cells called melanocytes, which are found within the hair, in the skin and in the eyes.  For the cat, the colour and pattern of the pigment within the hair is the most important. Summary of series List of alleles for reference. Eye colours Brown, amber and blue. Curly Coat is an interesting trait coded for by the K gene.  Dominant mutations (Ks) give the hair coat of the Selkirk Rex, while recessive mutations (kre, khr) give the hair coat of the Devon Rex and the Sphinx, respectively. These “ticked” hairs are typically alternated with a solid color, resulting in tabby stripes. Mink is created when a cat has ONE copy of Burmese and ONE copy of Siamese , as it is an intermediate color that is the co-dominace of the two together (cb/cs). But yet another gene is responsible for coding in color to dilute cats. The color gene for red is the only color gene attached to the sex of the cat.

Some info about the genetics behind it too! Silver is a gene that modifies yellow pigment to a silver colour but does not effect black pigment.  Unfortunately, the Silver gene is not as yet cloned. The current coat color panel does cover everything possible in a traditional Aby breeding program like cinnamon and dilute as well as agouti. If the cat retains any spot of another color on the coat, he is no longer considered a solid. 2. Breeding Punnet squares and a big Labrador case study. Liver The B series. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. The cat family (Felidae) exhibits a wide diversity of coat colors and patterns, including melanism in at least 11 species and different color “phases” in several others. Liver The B series. An example of polygenes influencing a major gene is the color of a red cat.  Colour pattern effects are produced by different levels of expression of the basic pigments, black and yellow, both between groups of hairs and also within the hair shaft itself.  Collectively, colour patterns are called Tabbies but this oversimplifies the genetics as there are several genes involved in giving patterned effects.  Tabbies require a normal functioning Agouti locus (A/-), and they will be masked in a black cat (a/a).  Tabby patterns can overlay the basic colour genes as well as the modifying colour genes.  Three genes associated with colour patterns are mentioned, including Classic Tabby, Ticked Tabby and Spotted Tabby. Dominant White, from Locus W, can give an all-white cat. The Dilution gene can also influence Orange pigmentation (Locus O), which it washes out to give a Cream coloration. In order for a cat to be lilac, it has to be a recessive homozygote for the primary gene for coat color (b/b), and it also has to be a recessive homozygote for the dense pigment gene (d/d).
