There are three alleles for this gene, with symbols B, b and bl respectively, in order of dominance. Welcome to the first DNA calculator that is combined with actual dogs and filters. Cat coat genetics: Summary of main genes. Entirely white coats in cats are produced by the pink-eyed albino genotype (cc), possibly by the pale-blue-eyed albino (caca or cac) or more likely by a quite separate mechanism known as dominant white. This article assumes you are familiar with basic Mendelian genetics- i.e. This can be seen in the self colored cat that still shows tabby patterns or barring. It has the effect of preventing the normal shift from eumelanin to phaeomelanin. The tabby markings show as a richer form of the red-based color, because the phaeomelanin has been inhibited to a lesser degree. FOREST CAT TORTOISESHELL-WHITE 9096 NORW. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. The normal or dominant form, C, is what might be termed 'full color'. Below are several documents to help you in this general context. Calculation accuracy of, the offspring color possibilities and probabilities can be greatly increased when providing the color genetics. The most important genes that affect pattern are the various tabby genes. Eumelanin is, in the absence of other modifying genes (see below), black or dark brown. The phaeomelanistic parts are affected by D and Dm in the usual way and tabby markings can continue through from the eumelanistic parts, this time showing as a richer red. Many of the other genes are simple recessives that have easy-to-understand effects. Tell us what you think of the coat calculator! The color gene for red is the only color gene attached to the sex of the cat. In some breeds this effect is undesirable, where it is sometimes called tarnishing e.g. FOREST CAT VAN DILUTE CALICO 9094 NORW. Software such as Breeders Assistant for Cats can help by taking the legwork out of working out the color gene combinations for any given mating. Burmese are ideally TaTa to reduce tabby markings whereas those with slight barring are more likely to be Tat or tt. There are currently four known alleles of the C locus in cats C, c s, c b, and c, with c being the most recessive and C being dominant. This gene has a lightening effect on eumelanin only. The blue dilution gene (D) also occurs, and works in the exact same way. If a cat is bb or bbl the brown is lightened to chocolate. After that search the color of the Female Cats (Dam/Female/Queen) in the right side and then click it again.. St. Austell Cornwall, PL25 3LB - ticked (as exemplified by the Abysinnian) ~1/2 white, color on head and torso. Phone: 850-386-1145 The cat will appear to be any of the above colors, but when the coat is parted you will see a white undercoat color. Thus in a tabby cat the hairs in the black parts where the tabby pattern shows through are eumelanin throughout, whereas in the other areas the typical agouti ticking is seen. They are responsible e.g. We like to refer to the color as Silver 13. Many dominant white cats are blue eyed, others are odd eyed. 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. A protein called the Agouti protein has a major effect on the 'injection' of melanin into the growing hair. More about Fife's ems codes: Maine Coon - Ems koder. These mutant forms are temperature sensitive - the higher the temperature, the more effective they are (i.e, the lighter the color). Grey Cat Names. nose leather in furred mammals. Next you enter the dam's color genotype in the same way. Solid Color Breeding Chart. We list some of the more well established ones here. This can really confuse matters. Another recessive gene responsible for the Cornish Rex (rr) coat. However, melanin is not added at a constant 'rate'. 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). Cat Coat Patterns. as check the box labeled gray to the right of your color selection. There are several forms of tabby pattern in the cat: When B is present (BB, Bb or Bbl) the brown/black eumelanin is its normal, unlightened, color. Cat coat genetics can give rise to a wide variety of colors and coat patterns. for tanning in humans, and for darker exposed skin e.g. the horses coat and will affect any color horse. The genes that interest us can be broadly classified as either: 1. become more understood, we will try to make changes to the calculator The Extension gene is also known as E-locus. Males can be O or o; females can be OO, Oo or oo. cs is the 'Siamese' factor; it has a much greater lightening effect than the Burmese allele and appears more temperature sensitive, with the points being considerably darker than the body. It is perhaps interesting to speculate whether this may in fact be the same as the K series of current thinking in dogs. Tallahassee, FL 32308 Siamese cats exhibit coat color typical for the temperature sensitive mutation within the C locus, which results in better pigment production at the colder extremities, which are cooler, such as the face, tip of the tail and paws. I.e, the hairs exhibit red-based rather than black-based colors. For a gray sire or dam, you must In this example we've set the dam to be Bbl Dd which means she is Seal point carrying blue and fawn. Blue Dilution - D gene: This recessive gene has a diluting effect on both eumelanin and phaeomelanin. Color Genes: genes that affect the pigment colorof hairs; OR 2. Where is Taffy? Breeders of red cats can selectively breed for these richer red tones e.g. The Dd part means he is carrying the recessive gene for blue dilution (d). Blue & White = Blue. Color codes: n - black a - blue d - red e - creme f - blacktortie g - bluetortie s - silver. … Genes for modification of the basic colours, including Brown (Locus B), Dilution (Locus D), and also Dilute-Modifier and Silver. Which makes him Chocolate carrying blue and fawn. FOREST CAT BI-COLOR 9092 NORW. Newer research indicates that 'dominant black' in dogs does not belong in the Agouti series at all but is a separate dominant gene (symbol K); the K series is also postulated as controlling brindle, with the brindle allele being intermediate between dominant black (K) and 'normal' (k). Polygenes control the length of the 'tail' - varying from no tail at all to a 'longie'. referred to as a Taffy. A black-and-white cat is considered to be easy-going. Phaeomelanin is, in its unmodified form, a yellowish color though cat breeders generally call it red. what the cat looks like) into consideration, which is why the colors red and creme are only shown with tabby, even though cats with these colors of course can be non-agouti genotypically. Chimeras (Cats Resulting from Fused Embryos) and Somatic Mutations. So far in this article we have only considered genes that affect coat color and pattern. MCO f, blacktortie. Patterns are combinations of colors in a specific layout.There are six basic varieties : Solid, Tabby, Bicolor, Tortoiseshell, Tricolor, and Colorpoint. Causes shortened long bones in all legs, but unlike a related form of dwarfism, Achondroplastic Dwarfism, it does not affect head size. Often these genes will always be the same 'state' for a given breed and are characteristic of that breed. - spotted (e.g. Black and White Cat Names. A Brown Burmese (US: Sable) will be slightly darker at the points but not markedly as in the Siamese. Please note that the color calculator only takes phenotypes (i.e. The important point is that it is affected. Lethal in the homozygote (MM). The mutant form has a greater effect on phaeomelanin(red) than eumelanin(black). In a cat that is not red (male o or female oo), or in the 'black' parts of a tortoiseshell (female Oo), the state of the Agouti gene is what affects whether any tabby patterning will be highly visible (A-) or hardly visible if at all (aa). In The USA: 800-514-9672 Phone: 850-386-1145 Email: Use Contact Form the gray horse can produce, it is necessary to know what color the This is my original calculator. advanced cat coat calculator The beefed up version of the calculator, with more genes and percentage chances! All cats registered under FIFe, has a pedigree with an EMS code. Melanin is produced by cells called melanocytes. Then in the mating certificate the predicted offspring gets a lot more interesting because the color distribution for the male and female kittens will be different. The intensity and pattern of these colors depends on the other genes involved in … - Seal in Siamese In the homozygote cc this causes complete absence of any pigment in both the fur and eyes: white fur and pink eyes (the pink color is simply the color of the blood). The Agouti protein causes a banding effect on the hair: it causes a fairly sudden change from the production of eumelanin (black/brown pigment) to phaeomelanin (red/yellow pigment). It is any solid colored or color pattern cat with markings that are white in color. However, there was no further breeding data to substantiate the claim, and perhaps even if correct the gene doesn't appear to be present in the present day pedigreed cat gene pool. 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. Coat color prediction is just one of many advanced features of Breeders Assistant for Cats Pro Edition, not found in any other pedigree breeding software we are aware of. USA, In The USA: 800-514-9672 The 'richness' of red coloration is also affected by what are known as 'rufous polygenes' (see below). Cool Cat Names; The term 'Agouti' actually refers to a South American rodent that exemplifies this type of hair. Red & White = Red. A dominant form of dwarfism characterised by the Munchkin breed (Mk-). A tortie female is Oo whereas a self-pointed female is oo. Dilute Calico = Blue-Cream. The 'richness' of phaeomelanin pigment is affected by what are known as 'rufous polygenes'.
