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. Breeding Punnet squares and a big Labrador case study. The Brown gene (Locus B) in the cat affects the intensity of black pigment. Summary of series List of alleles for reference. 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. I've depicted this on a black cat, but any colour or pattern can have white markings. 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. White Cats Eye Colours And Deafness Cat Genetics 2 0 Colours Laboratoire De Génétique Vétérinaire Cat Coat Pattern Genetics Agouti Gene. 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. Paw Print Genetics offers testing for common coat colors and traits. 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. Persian Cat Color Calculator Index.  Although the Ticked Tabby locus is distinct from the Classic Tabby locus, it can be masked by the Classic Tabby patterns. This is my original calculator. Bicolor (Black and White Bicolor) ~1/2 white, color on head and torso. Understanding the Basic Genetics of Cat Colors Some info about the genetics behind it too! Asking me to identify your cat's colour is a waste of my time and I won't respond. 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 . 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 color gene for red is the only color gene attached to the sex of the cat. Cat eyes can come in a variety of colors. DNA Testing. Although they are not shown on the chart, Tortoiseshell cats can also have tabby patterns. These cats are at a higher risk from congenital deafness and skin cancer. Mitted (Black Mitted) Just white paws. The classic calculator, simplified for ease of use. 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 … Amber Norwegian Forest Cats and Russet Burmese - Late Colour Change Genes (Extension Gene)  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. If the cat retains any spot of another color on the coat, he is no longer considered a solid. Nose colours From black to pink and everything inbetween. In a tortoiseshell tabby, or "torbie", the same tabby pattern is applied to both the red patches and the black patches. 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).  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. Coat and Color Descriptions. Leave a Reply Cancel reply. The influence of polygenes is what is responsible for the variation in the color of the red coat. 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. true color of the cat. Other Coat Patterns Tuxedo Cats Coloration with white paws, chest, and belly, with optional white on face. • We simply make changes to the genotype to make a cat look non-black and non-tabby. Pointed Color Chart. The current coat color panel does cover everything possible in a traditional Aby breeding program like cinnamon and dilute as well as agouti. Cat coat genetics: Lenght and texture. 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 full series (get the book! Van (Red Mackeral Tabby Van) Mostly white, color mainly on head and tail. Tabby coat pattern in cats. While fur color has little to do with eye color, breed certainly may. This information is not meant to be a complete manual on cat genetics. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. The tests for those variants have been combined for simplicity in ordering. Explore. Basic Feline Genetics. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. Hints for Determining Color.  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).

Eye colours Brown, amber and blue. 2. The agouti gene is what determines whether each hair will be a solid color, or will be a gradient from one color to another.  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. 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 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. To learn more, just click any of the coat color or trait names below. 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”. Dilution (blue and isabella) The D series. A short video explaining some of the genetics of cat coat colour. The color of a bicolor is determined by the non-white color of the cat… 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. color and pattern glossary . 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.  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. If the cat retains any spot of another color on the coat, he is no longer considered a solid. Locus E, also known as Extension, is an important gene for allowing black pigment production. Liver The B series.  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 White Gloving pattern seen in the Birman breed is caused by a mutation in the Kit gene, and displays recessive genetics. true color of the cat. Cat eye color is due to the presence of melanin, which itself is the result of genetics. Color and Pattern Genetics • There are many genes which contribute heavily to the appearance of every cat. Eye colours are associated with coat colours. Cat Genetics‎ > ‎ C. Dilute Colors (Gray, Lilac, Fawn ... D-(dense) dm-(NO dilute modifier) Dm-(dilute modifier, only affects a cat's coat IF the cat is homozygous recessive for dilute.) 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. • **Every cat is tabby. A. 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. … 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. Understanding the Basic Genetics of Cat Colors In the UK, solids are known as “self-colored” or “selfs.” Solid white cat. © 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 – Feline Blood Groups, Canine Disease Profile – PRA-Type-1 Papillons, Canine Disease Profile – Degenerative Myelopathy (DM), Canine Disease Profile – Multi-Drug Resistance (MDR1). Harlequin 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. Hints for Determining Color. Smoke cats. Categories Cute cat Images. 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. Dominant White, from Locus W, can give an all-white cat. For a visual representation of colour genetics covered in this article, see the colour chart Cat Genetics 2.1: Colours Chart. Locket (Blue Locket) White spot on chest. 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. washing it out.  Modifying genes include 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”.
