What is the common way to distinguish the Manx cat because of the 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.
Russian White, Black and Tabby The Russian White, Russian Black, and Russian Tabby are breeds of cat created in 1971, derived from the Russian Blue. The Black and Tabby Russians came from the original mating which created the Russian White. It is appropriate to consider their origins first.
