The wild-type dominant A gene will result in individual cat hairs having bands of color. Cat coat genetics: Lenght and texture. Cat Color Genetics White. kitten generator . The full series (get the book! A. washing it out.  Modifying genes include Brown (Locus B), Dilution (Locus D), and also Dilute-Modifier and Silver. Many white cats are born with a spot of color on their heads, and that color will indicate the true color of the cat. Coat and Color Descriptions. • We simply make changes to the genotype to make a cat look non-black and non-tabby. Jul 19, 2015 - COLOUR AND PATTERN CHARTS for every cat color in existence. Basic Feline Genetics. 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. Color and Pattern Genetics • There are many genes which contribute heavily to the appearance of every cat.  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. 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. Some genes have more than one mutation, such as those genes involved in Agouti and determining a brown coat color. Harlequin The rest of the color genes are actually patterns that affect the black or red. color and pattern glossary .  The White Gloving pattern seen in the Birman breed is caused by a mutation in the Kit gene, and displays recessive genetics. Coat Colours.  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. Pointed Color Breeding Chart. Genes for modification of the basic colours, including Brown (Locus B), Dilution (Locus D), and also Dilute-Modifier and Silver. 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). But yet another gene is responsible for coding in color to dilute cats. An example of polygenes influencing a major gene is the color of a red cat. Random-bred cats have the widest range of eye colours while the eye colours in pedigree breeds have been restricted by selective breeding. Some info about the genetics behind it too! Locket (Blue Locket) White spot on chest. The wild-type dominant A gene will result in individual cat hairs having bands of color. 5. Eye colours are associated with coat colours. Mitted (Black Mitted) Just white paws. Generate kittens using actual genetics! The mechanism of formation of this color is similar to that of the smoke color. 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. White cats eye colours and deafness cat genetics 2 0 colours laboratoire cat genetics 2 0 colours laboratoire cat genetics 2 0 colours laboratoire. Cat Colors FAQ: Cat Color Genetics. 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. Hints for Determining Color. These “ticked” hairs are typically alternated with a solid color, resulting in tabby stripes. Dilution (blue and isabella) The D series. 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. Basic Feline Genetics. The color gene for red is the only color gene attached to the sex of the cat.  The recessive and normal version of the gene is called w.  Dominant White will mask the effects of the Colorpoints (Locus C), Agouti (Locus A), and Brown and Cinnamon (Locus B).   Dominant white can be confused with recessive white (albino, c/c, coming from the C locus).  Unfortunately, Dominant white can be associated with deafness, particularly when it is present in two copies (W/W). The agouti gene is what determines whether each hair will be a solid color, or will be a gradient from one color to another. These are the genes that modify the colours … Cat Coat Color and Hair Traits; Cat Genetics 1.0: The Basics; Cat Genetics 2.0: Colors; Cat Genetics 2.1: Colours Chart; Cat Genetics 4.0: Evolution, Breeds, Breeding Strategies and Inbreeding; Cat Genetics 4.1: Inbreeding Calculator, Detailed Instructions and Interpretation; Cow. For those who would rather not try to remember everything, there is a color prediction software program available free for download: Feline Genetics Primer and FREE Feline Genetics Software Free program for predicting phenotypes of cats based on known genotypes, and calculating mating predictions. 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. Cat Coat Color and Hair Traits; Cat Genetics 1.0: The Basics; Cat Genetics 2.0: Colors; Cat Genetics 2.1: Colours Chart; Cat Genetics 4.0: Evolution, Breeds, Breeding Strategies and Inbreeding; Cat Genetics 4.1: Inbreeding Calculator, Detailed Instructions and Interpretation; Cow. These cats are at a higher risk from congenital deafness and skin cancer. Basic Feline Genetics. While fur color has little to do with eye color, breed certainly may. In the UK, solids are known as “self-colored” or “selfs.” Solid white cat. 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. Many white cats are born with a spot of color on their heads, and that color will indicate the true color of the cat. To learn more, just click any of the coat color or trait names below. Amber Norwegian Forest Cats and Russet Burmese - Late Colour Change Genes (Extension Gene)  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). Solid Color Breeding Chart. We will primarily talk about 11 genes. Cat eye color is due to the presence of melanin, which itself is the result of genetics.

Such a coat looks like a solid color until you blow on it or the cat's … 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. Other Coat Patterns Tuxedo Cats Coloration with white paws, chest, and belly, with optional white on face. Required fields are marked * Comment. 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.

Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. Some info about the genetics behind it too! In the UK, solids are known as “self-colored” or “selfs.” Solid white cat.  While a comprehensive understanding of the genetics of white spots in cats remains for the future, some breed specific advances have been made. ... Sex-Linked Red Color Combinations Chart Colorpoint Shorthair & Persian-Himalayan. The Brown gene (Locus B) in the cat affects the intensity of black pigment. 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. 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. We have just talked about the genetics of cat colours. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. Basic genetics terms Genes, locii etc. If you're new to the cat genetics world, here's a guide to colors and patterns with plenty of pictures! 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”. Feline Coat Color Introduction The modern-day domestic cat displays a wide variety of coat colors and patterns. • **Every cat is tabby. 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).  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. Smoke cats. Bicolor (Black and White Bicolor) ~1/2 white, color on head and torso. 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).  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.  The genetics of cat coloration is a good practical example of basic genetics and of heredity.  We will see the function of single genes, the passage of genes to the next generation, and importantly, the interaction of genes with each other to give the combinations of colour traits seen between and within the cat breeds. Your email address will not be published. Hints for Determining Color. 2. The tests for those variants have been combined for simplicity in ordering.

The Dilution gene can also influence Orange pigmentation (Locus O), which it washes out to give a Cream coloration. 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. The dilute … But you may be thinking after part B., HEY! After birth, over some weeks the silver fur is replaced naturally by fur colored according to the kitten's genetics. 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. Coat and Color Descriptions. Harlequin  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. Dominant White, from Locus W, can give an all-white cat. Cat Coat Pattern Genetics Agouti Gene. Basic genetics terms Genes, locii etc. Nose colours From black to pink and everything inbetween. Asking me to identify your cat's colour is a waste of my time and I won't respond. Some genes are simplified and it does not give percentage changes, but it should be easy to use even if you know very little about genetics. This is the most common coat pattern in the wild and it has four varieties: Striped (Mackerel), blotched (marbled), spotted, and ticked (agouti). 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. This information is not meant to be a complete manual on cat genetics. Bicolor (Black and White Bicolor) ~1/2 white, color on head and torso. The white spotting gene causes variable white markings. This is the most common coat pattern in the wild and it has four varieties: Striped (Mackerel), blotched (marbled), spotted, and ticked (agouti). Cat coat length is controlled by the gene named the fibroblast growth factor 5 (FGF5). Breeding Punnet squares and a big Labrador case study. If the cat retains any spot of another color on the coat, he is no longer considered a solid. ): Guide to Pantherinae/Big cats Guide to Felinae/Little cats Guide to Housecat breeds 1 Guide to Housecat breeds 2 Guide to Coat colors and Patterns advanced cat coat calculator The full calculator with percentage chances. 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. 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. Cat fur color is a common teaching tool in biology and genetics classes. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. Similar color charts have appeared in Wright & Walters (The Book of the Cat, 1980) and in Robinson's Genetics (1977 onwards) and all of this information on this page has … 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. 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”. 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. Liver The B series. DNA Testing. Pointed Color Chart. For a visual representation of colour genetics covered in this article, see the colour chart Cat Genetics 2.1: Colours Chart.

Maybe think of them as primary colors in the color wheel. We should also mention the heredity of cat colours, that is to say, the passage of the genes for coat colours from one generation to the next.  To help the discussion, think of the cat genome as a deck of playing cards (see Cat Genetics 1.0: The Basics) where each gene (or card) is represented twice.  From this deck of cards, with its own particular combination of cards is constructed a house of cards, or in this instance, a cat.  Between generations, the house of cards is collapsed and the deck of cards gets shuffled and then cut in two.  A new house (cat) is built from a new combination of cards, half coming from mom and the other half from dad.  When you think of all the known genes with all their variations that are involved in establishing the colour of a cat, then add in the genes not as yet characterised, this can give a whole lot of new possible combinations between generations.  That’s genetics.  And the challenge of breeding.
