This is a pattern in which the cat has a solid base color, but the bottom eighth of each hair is white or creamy. 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. This information is not meant to be a complete manual on cat genetics. Understanding the Basic Genetics of Cat Colors ): 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 Pointed Color Chart.  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. If the cat retains any spot of another color on the coat, he is no longer considered a solid. 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. 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. Van (Red Mackeral Tabby Van) Mostly white, color mainly on head and tail. This is my original calculator. The rest of the color genes are actually patterns that affect the black or red. 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. 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 Brown gene (Locus B) in the cat affects the intensity of black pigment. We have just talked about the genetics of cat colours. Feline Coat Color Introduction The modern-day domestic cat displays a wide variety of coat colors and patterns. In the UK, solids are known as “self-colored” or “selfs.” Solid white cat. The wild-type dominant A gene will result in individual cat hairs having bands of color. When the term COLOR is used, it refers to color …  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. Read more about cat color and genetics on Paws and Effect >> When it comes to coat patterns, hereâs a mind-blowing fact: All cats start as tabbies. Smoke cats. color and pattern glossary . kitten generator . A. The following statements are generally true – but there are exceptions. 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. Thatâs genetics. And the challenge of breeding. Cats can have a full range of white markings, from none, to moderate, to predominant. The Locus S is involved in producing white markings, but the gene has not been cloned and it is not known if Locus S represents one gene or several genes. The influence of polygenes is what is responsible for the variation in the color of the red coat. White Cats Eye Colours And Deafness Cat Genetics 2 0 Colours Laboratoire De Génétique Vétérinaire Eye colours Brown, amber and blue. Other Coat Patterns Tuxedo Cats Coloration with white paws, chest, and belly, with optional white on face. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. Nose colours From black to pink and everything inbetween. A short video explaining some of the genetics of cat coat colour. Understanding the Basic Genetics of Cat Colors Leave a Reply Cancel reply. For more information, please refer to books on the subject. Cat Colors FAQ: Cat Color Genetics. These cats are at a higher risk from congenital deafness and skin cancer. The two basic pigments that contribute to coloration are black and yellow pigments. It is the interplay between the expression of genes for these two basic pigments that give the cat its basic coloration. 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. The effect of polygenes is cumulative on coat color genetics. Cat eye color is due to the presence of melanin, which itself is the result of genetics. After birth, over some weeks the silver fur is replaced naturally by fur colored according to the kitten's genetics. Photography by Casey Elise Photography. 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. The Dilution gene can also influence Orange pigmentation (Locus O), which it washes out to give a Cream coloration. The dilute … Coat Colours. 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. White cats eye colours and deafness cat genetics 2 0 colours laboratoire cat genetics 2 0 colours laboratoire cat genetics 2 0 colours laboratoire. The agouti gene is what determines whether each hair will be a solid color, or will be a gradient from one color to another. If the cat retains any spot of another color on the coat, he is no longer considered a solid. Your email address will not be published. These are the genes that modify the colours … Harlequin 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 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. 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. Tabby coat pattern in cats. true color of the cat. 5. Liver The B series.  Although the Ticked Tabby locus is distinct from the Classic Tabby locus, it can be masked by the Classic Tabby patterns. Locket (Blue Locket) White spot on chest. Jul 19, 2015 - COLOUR AND PATTERN CHARTS for every cat color in existence. 2. The wild-type dominant A gene will result in individual cat hairs having bands of color. washing it out. Modifying genes include Brown (Locus B), Dilution (Locus D), and also Dilute-Modifier and Silver. Random-bred cats have the widest range of eye colours while the eye colours in pedigree breeds have been restricted by selective breeding. Many white cats are born with a spot of color on their heads, and that color will indicate the true color of the cat. The classic calculator, simplified for ease of use. 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. Some info about the genetics behind it too! While fur color has little to do with eye color, breed certainly may. Dilution (blue and isabella) The D series. The color of a bicolor is determined by the non-white color of the cat⦠Genes for modification of the basic colours, including Brown (Locus B), Dilution (Locus D), and also Dilute-Modifier and Silver.

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”. If you're new to the cat genetics world, here's a guide to colors and patterns with plenty of pictures! Name * The current coat color panel does cover everything possible in a traditional Aby breeding program like cinnamon and dilute as well as agouti. Maybe think of them as primary colors in the color wheel. Kittens are born blind.  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. Bi-Color to Bi-Color Color Calculator; Bi-Color to Bi-Color Van Color Calculator The agouti gene is what determines whether each hair will be a solid color, or will be a gradient from one color to another. 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. 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 … Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. Pointed Color Breeding Chart. 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. Explore. 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 White Gloving pattern seen in the Birman breed is caused by a mutation in the Kit gene, and displays recessive genetics. 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. Cats are known for their striking colour patterns, including stripes, spots and swirls of colour. When it comes to colour patterns, dogs are poor cousins to cats. • **Every cat is black. 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. 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 eyes can come in a variety of colors. The tests for those variants have been combined for simplicity in ordering. 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). 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 Pattern Genetics Agouti Gene. Basic Feline Genetics. Eye colours Brown, amber and blue. Dilution (blue and isabella) The D series. Summary of series List of alleles for reference. Feline Coat Color Introduction The modern-day domestic cat displays a wide variety of coat colors and patterns. Both of the cats above have the same major allele – O – which is responsible for their red coats. Colour and pattern charts color genetics american exotic cats cat color genetics metafilter genetics cat coat color and pattern warriors amino. 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 âmasksâ. Cat coat genetics: Lenght and texture.  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). cat coat calculator . I've depicted this on a black cat, but any colour or pattern can have white markings. Coat and Color Descriptions. true color of the cat. The Orange gene (Locus O) is interesting for two reasons. First of all, it is unique to cats. Summary of series List of alleles for reference. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. Amber Norwegian Forest Cats and Russet Burmese - Late Colour Change Genes (Extension Gene) Color and Pattern Genetics • There are many genes which contribute heavily to the appearance of every cat. Cat Coat Pattern Genetics Agouti Gene. Although they are not shown on the chart, Tortoiseshell cats can also have tabby patterns. Generate kittens using actual genetics! This is the most common coat pattern in the wild and it has four varieties: Striped (Mackerel), blotched (marbled), spotted, and ticked (agouti). An example of polygenes influencing a major gene is the color of a red cat. **Mink isn't a single color allele (which is why it isn't a choice above). • **Every cat is tabby. Basic Feline Genetics. Basic Feline Genetics. Coloration is a physical trait of cats that is visible, is not associated with disease conditions (with some exceptions), and that has been desirable since the beginning of the development of cat breeds. 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. Eye colours are associated with coat colours. 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. 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). 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. Locus E, also known as Extension, is an important gene for allowing black pigment production. For example, in the small Neotropical jaguarundi ( Herpailurus yaguarondi ), coloration varies from dark brown/gray (the most common form, widely regarded as the wild-type) to light reddish 1 , 2 . But yet another gene is responsible for coding in color to dilute cats. Breeding Punnet squares and a big Labrador case study. Bicolor (Black and White Bicolor) ~1/2 white, color on head and torso. Some info about the genetics behind it too! For the Love of Gray Cats! Mitted (Black Mitted) Just white paws. In a tortoiseshell tabby, or "torbie", the same tabby pattern is applied to both the red patches and the black patches. Cat coat length is controlled by the gene named the fibroblast growth factor 5 (FGF5). Harlequin The color gene for red is the only color gene attached to the sex of the cat. advanced cat coat calculator The full calculator with percentage chances. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. Nose colours From black to pink and everything inbetween.  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 simplicityâ¦.will pretty quickly give us complexity. Although they are not shown on the chart, Tortoiseshell cats can also have tabby patterns. Breeding Punnet squares and a big Labrador case study.  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). Tabby coat pattern in cats. Photography by Casey Elise Photography. Jul 19, 2015 - COLOUR AND PATTERN CHARTS for every cat color in existence. 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. Hints for Determining Color. cat coat calculator (original ver.) Categories Cute cat Images. Cat fur color is a common teaching tool in biology and genetics classes. 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 âCarmelâ shades of colours while Locus O (Orange) gives Apricot. The Dilute-Modifier gene is not as yet cloned or characterized. Many white cats are born with a spot of color on their heads, and that color will indicate the true color of the cat. This FAQ covers common cat colors, basic color terminology, and color genetics.
