Below is a table of the coat color genes and dna tests offered by the veterinary genetics laboratory. The gene c (colour), dominant over all others is mutated into cb.
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!
Burmese cat colour genetics. 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. This burmese gene creates a brownish coat for a genetically black cat (sable burmese). 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.
The mutations described above have been seen and described in cats in europe and and the western hemisphere for hundreds of years. Joseph thompson of san francisco brought a small walnut brown female cat from burma. Through selective breeding the unique solid brown colored coat, now known as sable, was isolated.
The cat fanciers association began registering burmese in 1936 but suspended registrations in 1947 because breeders were still using. The gene responsible for burmese is known as cb. 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.
Colour mating chart for brown, blue, chocolate and lilac burmese showing percentages of colours which might be expected over a number of litters. Then, what is a patched tabby? Siamese express the temperature dependent pigmentation the most evidently, with darker parts of the coat in the ears, muzzle, feet and tail tip.
The american burmese and the british burmese (and are not to be confused with sacred cat of burma, in respect of which, see birman). The burmese carries the gene for sepia color (cb) and the siamese carries the gene for pointed color (cs). Another set of mutations of colour has been introduced with the siamese and burmese cats from asia.
The burmese gene is a variation of the albino serial. 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. The burmese breed first came to america in 1930 when dr.
Burmese are good climbers and jumpers and should have cat trees and perches. 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. 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.
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 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). 1959 saw more colour variations, along came the chocolate and the lilac and 1964 saw the red, cream, lilac and the torties.
The burmese cat should be of a small to medium size with good muscular development, with slightly stockier legs than that of the siamese. Although this colour is typical for the burmese cat breed, not all burmese possess this gene. Most modern burmese are descendants of one female cat called wong mau, which.
He named her wong mau and bred her to siamese cats. The genetics of cat coloration is a good practical example of basic genetics and of heredity. Burmese cats are recognized by their dark sepia brown coat colour which is a result of the c b gene.
Most cat registries do not recognise a split between the two groups, but those that do. While adult burmese are placid cats, they also tend to be very kittenish and love their daily playtime. Another set of mutations of color has been introduced with the siamese and burmese cats from asia.
Thongdaeng or supphalak, meaning copper colour) is a breed of domestic cat, originating in southeast asia and developed in the united states and britain. Intermediate between these is the mink pattern (tonkinese colour restriction) caused when the siamese and burmese colour restriction genes interact. 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.
This faq covers common cat colors, basic color terminology, and color genetics. The typical burmese appearance can be traced back to the homozygous recessive gene cb. Affiliated to the governing council of the cat fancy the burmese cat club.
4/1943 journal of heredity genetics of the burmese cat Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently. It can also be with, or without, white.
The points may be solid, tabby or tortie colours. While the burmese is a pointed cat, the contrast between the points and the body colour isn’t quite as defined as that of the siamese. Intermediate between these is the mink pattern (tonkinese colour restriction) caused when the siamese and burmese colour restriction genes interact.
The blue and black (brown) colors can also be combined with red in a tabby pattern to make the cat a patched tabby. The burmese carries the gene for sepia colour (cb) and the siamese carries the gene for pointed colour (cs). The points may be solid, tabby or tortie colours.
