Burmese cat 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). The same gene can also be combined with the Siamese gene (cbcs) to produce either darker points or a light-on-dark-brown coat, similar to the Burmese chocolate/champagne, known as "mink". The Asian domestic cat breed is related to the Burmese; the Asian is physically similar but comes in different patterns and colours. The Singapura is always homozygous for the Burmese gene, combining it with a ticked tabby pattern. Snow Bengals
Cat body-type mutation Cat body-type mutation Cats, like all living organisms, occasionally have mutations that affect their body type. Sometimes, these cat body-type mutations are striking enough that humans select for and perpetuate them. This is not always in the best interests of the cat, as many of these mutations are harmful; some are even lethal in their homozygous form. This page gives a selection of cat body type mutant alleles and the associated mutations with a brief description. Jb = Japanese bobtail gene (autosomal dominant). Cats homozygous and heterozygous for this gene display shortened and kinked tails. Cats homozygous for the gene
