DSH cats in Asia tend to have a build similar to a "classic" Siamese or Tonkinese, while European and American varieties have a thicker, heavier build. Mixed-breed domestic cats have a form of hybrid
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
