Understanding the basic genetics of cat colors a presentation of the cat fanciers association, inc. Although this colour is typical for the burmese cat breed, not all burmese possess this gene.
Another set of mutations of colour has been introduced with the siamese and burmese cats from asia.
Burmese cat colour genetics. 4/1943 journal of heredity genetics of the burmese cat Siamese express the temperature dependent pigmentation the most evidently, with darker parts of the coat in the ears, muzzle, feet and tail tip. Then, what is a patched tabby?
Colour mating chart for brown, blue, chocolate and lilac burmese showing percentages of colours which might be expected over a number of litters. The burmese gene is also present in some other cat breeds, particularly the established rex breeds, where it can be fully expressed in its homozygous form (cbcb) (referred to as burmese colour restriction or sepia). Most cat registries do not recognise a split between the two groups, but those that do.
The burmese carries the gene for sepia colour (cb) and the siamese carries the gene for pointed colour (cs). Through selective breeding the unique solid brown colored coat, now known as sable, was isolated. Most modern burmese are descendants of one female cat called wong mau, which.
Affiliated to the governing council of the cat fancy the burmese cat club. Most modern burmese are descendants of one female cat called wong mau, which was brought from burma to america in 1930 and bred with american siamese. Burmese are good climbers and jumpers and should have cat trees and perches.

The typical burmese appearance can be traced back to the homozygous recessive gene cb. This burmese gene creates a brownish coat for a genetically black cat (sable burmese). The burmese is a domestic breed of cat which originated in burma (now myanmar) and was developed in the united states and the united kingdom.
Below is a table of the coat color genes and dna tests offered by the veterinary genetics laboratory. It can also be with, or without, white. The burmese gene is a variation of the albino serial.
Formed in 1955, and one of the largest clubs, we exist to safeguard the wellbeing and the purity of the breed, and to encourage a wider appreciation of the unique qualities of burmese cats. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. The burmese cat should be of a small to medium size with good muscular development, with slightly stockier legs than that of the siamese.
Two copies of the burmese allele (cb) are required for burmese colouration and cause a change from black to sepia and orange to yellow, with the points being darker than the body. He named her wong mau and bred her to siamese cats. 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.
The gene c (colour), dominant over all others is mutated into cb. The mutations described above have been seen and described in cats in europe and and the western hemisphere for hundreds of years. Intermediate between these is the mink pattern (tonkinese colour restriction) caused when the siamese and burmese colour restriction genes interact.
The burmese cat is a domestic cat breed that hails from thailand, which is renowned for its playful nature regardless of age, and its vocal meow that it is not afraid to use! The cat fanciers association began registering burmese in 1936 but suspended registrations in 1947 because breeders were still using.

The first cats of the burmese breed were uniformly sable (dark brown) in colour, although now they can be seen in a much wider range of colours.
The burmese carries the gene for sepia color (cb) and the siamese carries the gene for pointed color (cs). The points may be solid, tabby or tortie colours. The blue and black (brown) colors can also be combined with red in a tabby pattern to make the cat a patched tabby.
The genetics of cat coloration is a good practical example of basic genetics and of heredity. This faq covers common cat colors, basic color terminology, and color genetics. Intermediate between these is the mink pattern (tonkinese colour restriction) caused when the siamese and burmese colour restriction genes interact.
Another set of mutations of color has been introduced with the siamese and burmese cats from asia. The results, including the discovery of the burmese gene, were so interesting that thompson published an article on the subject in a 1943 issue of the journal of heredity, the first such piece on feline genetics. Joseph thompson of san francisco brought a small walnut brown female cat from burma.
The burmese is a sturdy, stocky cat and her nutrition should be watched to prevent obesity, particularly if the cat does not get enough exercise. Burmese cats are recognized by their dark sepia brown coat colour which is a result of the c b gene. 1959 saw more colour variations, along came the chocolate and the lilac and 1964 saw the red, cream, lilac and the torties.
The gene responsible for burmese is known as cb.
