These are the genes that modify the colours … DNA Testing. Paw Print Genetics offers testing for common coat colors and traits. Maybe think of them as primary colors in the color wheel. The current coat color panel does cover everything possible in a traditional Aby breeding program like cinnamon and dilute as well as agouti. 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”. advanced cat coat calculator The full calculator with percentage chances. Understanding the Basic Genetics of Cat Colors Cat Colors FAQ: Cat Color Genetics. 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. 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 info about the genetics behind it too! Categories Cute cat Images. 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. Locket (Blue Locket) White spot on chest. This is my original calculator. true color of the cat. Harlequin Summary of series List of alleles for reference. **Mink isn't a single color allele (which is why it isn't a choice above). The tests for those variants have been combined for simplicity in ordering. Genes for modification of the basic colours, including Brown (Locus B), Dilution (Locus D), and also Dilute-Modifier and Silver. This is the most common coat pattern in the wild and it has four varieties: Striped (Mackerel), blotched (marbled), spotted, and ticked (agouti). 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. Amber Norwegian Forest Cats and Russet Burmese - Late Colour Change Genes (Extension Gene) 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. Other Coat Patterns Tuxedo Cats Coloration with white paws, chest, and belly, with optional white on face.  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. Breeding Punnet squares and a big Labrador case study. In a tortoiseshell tabby, or "torbie", the same tabby pattern is applied to both the red patches and the black patches. Other Coat Patterns Tuxedo Cats Coloration with white paws, chest, and belly, with optional white on face. Feline Coat Color Introduction The modern-day domestic cat displays a wide variety of coat colors and patterns.  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). 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 wild-type dominant A gene will result in individual cat hairs having bands of color.

Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. But you may be thinking after part B., HEY! 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. Bi-Color to Bi-Color Color Calculator; Bi-Color to Bi-Color Van Color Calculator Generate kittens using actual genetics! Such a coat looks like a solid color until you blow on it or the cat's … Basic genetics terms Genes, locii etc. The influence of polygenes is what is responsible for the variation in the color of the red coat. We have just talked about the genetics of cat colours. I've depicted this on a black cat, but any colour or pattern can have white markings. COLOUR AND PATTERN CHARTS - downloadable charts for breeders, tutorials etc CONFORMATION CHARTS - downloadable charts for breeders, tutorials etc Plain English Guide to Colours and Patterns Plain English Guide to Conformation. Dilution (blue and isabella) The D series. 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. color and pattern glossary .  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. Photography by Casey Elise Photography. Random-bred cats have the widest range of eye colours while the eye colours in pedigree breeds have been restricted by selective breeding. Basic Feline Genetics. Eye colours are associated with coat colours. Pointed Color Breeding Chart. Understanding the Basic Genetics of Cat Colors The color gene for red is the only color gene attached to the sex of the cat. Breeding Punnet squares and a big Labrador case study. 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. … For the Love of Gray Cats! 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. 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. 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.  While a comprehensive understanding of the genetics of white spots in cats remains for the future, some breed specific advances have been made. If the cat retains any spot of another color on the coat, he is no longer considered a solid. In the UK, solids are known as “self-colored” or “selfs.” Solid white cat. Both of the cats above have the same major allele – O – which is responsible for their red coats. The effect of polygenes is cumulative on coat color 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. Cat Color Genetics White. The following statements are generally true – but there are exceptions. Locus E, also known as Extension, is an important gene for allowing black pigment production. Basic genetics terms Genes, locii etc. Nose colours From black to pink and everything inbetween.

Photography by Casey Elise Photography. The Orange gene (Locus O) is interesting for two reasons.  First of all, it is unique to cats. Genetic Disorders. Jul 19, 2015 - COLOUR AND PATTERN CHARTS for every cat color in existence. After birth, over some weeks the silver fur is replaced naturally by fur colored according to the kitten's genetics. 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. The eye is blueish as it first starts to develop, gradually becoming the final adult color at three months. Explore. Required fields are marked * Comment. 2. Eye colours Brown, amber and blue.  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. Tabby coat pattern in cats. 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. 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. This information is not meant to be a complete manual on cat genetics. These “ticked” hairs are typically alternated with a solid color, resulting in tabby stripes. 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 … 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). Hints for Determining Color.  The White Gloving pattern seen in the Birman breed is caused by a mutation in the Kit gene, and displays recessive genetics. 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. Cat fur color is a common teaching tool in biology and genetics classes. 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. Name * Genetics & Cat Colors. Cat Coat Pattern Genetics Agouti Gene. To determine what color your Persian kitten will be, use the Color Calculator by choosing the color of the Father mated to the color of the Mother in the Index below (shown in alphabetical order). 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 Coat Pattern Genetics Agouti Gene. • We simply make changes to the genotype to make a cat look non-black and non-tabby. The mechanism of formation of this color is similar to that of the smoke color. Colour and pattern charts color genetics american exotic cats cat color genetics metafilter genetics cat coat color and pattern warriors amino. true color of the cat. Smoke cats. The rest of the color genes are actually patterns that affect the black or red. 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). Asking me to identify your cat's colour is a waste of my time and I won't respond. Harlequin 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 eye color is due to the presence of melanin, which itself is the result of genetics. Nose colours From black to pink and everything inbetween. Summary of series List of alleles for reference. To learn more, just click any of the coat color or trait names below.  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. Pointed Color Chart.  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).  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. When the term COLOR is used, it refers to color … 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. Van (Red Mackeral Tabby Van) Mostly white, color mainly on head and tail. Mitted (Black Mitted) Just white paws. Liver The B series. Van (Red Mackeral Tabby Van) Mostly white, color mainly on head and tail. 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 white spotting gene causes variable white markings. But yet another gene is responsible for coding in color to dilute cats. Bicolor (Black and White Bicolor) ~1/2 white, color on head and torso. If the cat retains any spot of another color on the coat, he is no longer considered a solid. The color of a bicolor is determined by the non-white color of the cat… Jul 19, 2015 - COLOUR AND PATTERN CHARTS for every cat color in existence. Eye colours Brown, amber and blue. 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. 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. Feline Coat Color Introduction The modern-day domestic cat displays a wide variety of coat colors and patterns. The dilute … Solid Color Breeding Chart. The Dilution gene can also influence Orange pigmentation (Locus O), which it washes out to give a Cream coloration. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. 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). Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. Liver The B series. Mitted (Black Mitted) Just white paws. 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. Resources: This review of the genetics of cat colours is not meant to be exhaustive.  It is the beginning of the story rather than the end of one.  Further information and details can be found on these websites: https://en.wikipedia.org/wiki/Cat_coat_genetics, http://homepage.usask.ca/~schmutz/catcolors.html, © 2020 Labgenvet / Tous droits réservés / All Rights Reserved, Dog Genetics 3.0: Simple Genetic Diseases, Dog Genetics 4.0: Evolution, Breeds, Breeding strategies and Inbreeding, Dog Genetics 4.1: Inbreeding Calculator, Detailed Instructions and Interpretation, Veterinary Continuing Education – Dog Genetics Demystified, Cat Genetics 4.0: Evolution, Breeds, Breeding Strategies and Inbreeding, Cat Genetics 4.1: Inbreeding Calculator, Detailed Instructions and Interpretation, Horse Genetics 4.0: Evolution, Breeds, Breeding Strategies and Inbreeding, Horse Genetics 4.1: Inbreeding Calculator, Detailed Instructions and Interpretation, Laboratory of Veterinary Genetics "For the genetic improvement of our domestic animals", Cat Genetic Profile – Hypertrophic Cardiomyopathy (HMC), Cat Genetic Profile – Feline Blood Groups, Canine Disease Profile – Degenerative Myelopathy (DM).
