Dilution (blue and isabella) The D series. Basic Feline Genetics. Liver The B series. Coat Colours. DNA Testing. Solid Color Breeding Chart. Nose colours From black to pink and everything inbetween. This is the most common coat pattern in the wild and it has four varieties: Striped (Mackerel), blotched (marbled), spotted, and ticked (agouti). Mackerel Tabby and Classic Tabby are caused by the same gene (Ta), with Mackerel being dominant over Classic Tabby.  In Classic (or Blotched) Tabby, swirls and blotches of black and yellow pigment occur.  Mackerel Tabby gives the familiar alternating stripes of black and yellow pigment seen in cats.  Think little tigers. 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. Genes for basic colours, including Colorpoint (Locus C), Agouti (Locus A), Orange (Locus O) and Locus E. These are the genes that make the pigments that give the basic colours to the cat. Cat Coat Pattern Genetics Agouti Gene. Cat Colors FAQ: Cat Color Genetics. Van (Red Mackeral Tabby Van) Mostly white, color mainly on head and tail. Read more about cat color and genetics on Paws and Effect >> When it comes to coat patterns, here’s a mind-blowing fact: All cats start as tabbies. Summary of series List of alleles for reference. Other Coat Patterns Tuxedo Cats Coloration with white paws, chest, and belly, with optional white on face. Leave a Reply Cancel reply. advanced cat coat calculator The full calculator with percentage chances. • We simply make changes to the genotype to make a cat look non-black and non-tabby.  Having said this, Locus E is not very important for most cat breeds although it is responsible for the Amber colour (e/e) that can be seen in the Norwegian Forest Cat breed.  Locus E is much more important in the dog and the horse where (e/e) is responsible for the beautiful golden coloration of the Golden Retriever dog and the rich red coloration of the Irish Setter dog and the Chestnut coloured horse (see Dog Genetics 2.0: Colours; Horse Genetics 2.0: Colours). Name * our genetic system is in duplicate (see Cat Genetics 1.0: The Basics).  Also, that the effect of one copy of a gene can be dominant over the other copy, which is said to be recessive.  For a given gene an individual cat can have two copies that are the same (either two dominant or two recessive copies), or one copy that is dominant and one copy that is recessive.  Furthermore, the functions of one gene can mask the functions of another gene.  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. The wild-type dominant A gene will result in individual cat hairs having bands of color. Secondly, it is found on the X chromosome, making the Orange coloration sex linked.  There are two versions of the gene, orange (O) and black (o).  Orange (O) blocks black pigment and allows only yellow pigment to be formed, while black (o) blocks yellow pigment and allows only black pigment to be formed.  Female cats, possessing two X chromosomes, can have orange fur (O/O), black fur (o/o), or a stylish mix of orange and black hairs to give Tortoiseshell fur (O/o).  Male cats, with only one X chromosome, can only have orange fur or black fur, and cannot be tortoiseshell.  The rare tortoiseshell males that do occasionally occur usually have an extra X chromosome (XXY).  Unfortunately, Orange is not as yet cloned, so we do not know what type of gene it is.  Functionally Orange acts a bit like the Agouti Dominant Yellow that is seen in dogs (see Dog Genetics 2.0: Colours).  Dogs do not have sex-linked colour patterns. Hints for Determining Color. Generate kittens using actual genetics! 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. Liver The B series. Coat and Color Descriptions. The effect of polygenes is cumulative on coat color genetics. Bicolor (Black and White Bicolor) ~1/2 white, color on head and torso. 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: Keep in mind that genes come in two copies, i.e. Cat Color Genetics White. The color gene for red is the only color gene attached to the sex of the cat. 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. The full series (get the book! Eye colours Brown, amber and blue. In the UK, solids are known as “self-colored” or “selfs.” Solid white cat. Basic genetics terms Genes, locii etc. 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.

This is the most common coat pattern in the wild and it has four varieties: Striped (Mackerel), blotched (marbled), spotted, and ticked (agouti). Summary of series List of alleles for reference.  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. For the Love of Gray Cats! kitten generator . Some info about the genetics behind it too! These are the genes that modify the colours … 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. These “ticked” hairs are typically alternated with a solid color, resulting in tabby stripes. 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. Photography by Casey Elise Photography. Cat fur color is a common teaching tool in biology and genetics classes. We will primarily talk about 11 genes. If the cat retains any spot of another color on the coat, he is no longer considered a solid. 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.  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. Locket (Blue Locket) White spot on chest. This information is not meant to be a complete manual on cat genetics. If the cat retains any spot of another color on the coat, he is no longer considered a solid. A.  Although the Ticked Tabby locus is distinct from the Classic Tabby locus, it can be masked by the Classic Tabby patterns. Categories Cute cat Images. 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. Nose colours From black to pink and everything inbetween. The current coat color panel does cover everything possible in a traditional Aby breeding program like cinnamon and dilute as well as agouti. Jul 19, 2015 - COLOUR AND PATTERN CHARTS for every cat color in existence. 2. The Abyssinian Homepage Color Inheritence Chart For Cats Colour and pattern charts colour and pattern charts colour and pattern charts cat colors get the fascinating facts behind coats patterns. Eye colours are associated with coat colours.  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. While fur color has little to do with eye color, breed certainly may. Although they are not shown on the chart, Tortoiseshell cats can also have tabby patterns. 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.

If you do not know what recessive colors your cat is carrying, then you may find out by sending a DNA sample to Veterinary Genetics Laboratory of UC Davis (USA). Asking me to identify your cat's colour is a waste of my time and I won't respond. Required fields are marked * Comment. The eye is blueish as it first starts to develop, gradually becoming the final adult color at three months. Some genes have more than one mutation, such as those genes involved in Agouti and determining a brown coat color. Generally speaking, a cat with one copy of the white spotting gene will be anywhere from 0% to 50% white while a cat with two copies of the gene will be anywhere from 50% to 100% white as shown on the chart. Understanding the Basic Genetics of Cat Colors Kittens are born blind. The white spotting gene causes variable white markings. 5.  It is important to realize that a single hair can be all black, all yellow, or have bands of black and yellow or even bands of modified black and yellow. The wild-type dominant A gene will result in individual cat hairs having bands of color. Many white cats are born with a spot of color on their heads, and that color will indicate the true color of the cat. When the term COLOR is used, it refers to color … Mitted (Black Mitted) Just white paws. Therefore, a cat that appears to be white will breed the same as any of the other colors shown above, depending upon which color it “masks”. Although they are not shown on the chart, Tortoiseshell cats can also have tabby patterns. ... Sex-Linked Red Color Combinations Chart Colorpoint Shorthair & Persian-Himalayan. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. true color of the cat. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. But yet another gene is responsible for coding in color to dilute cats. Eye colours Brown, amber and blue. Smoke cats. Random-bred cats have the widest range of eye colours while the eye colours in pedigree breeds have been restricted by selective breeding. Jul 19, 2015 - COLOUR AND PATTERN CHARTS for every cat color in existence.
