Summary of population genetics of cat breeds and populations. Random bred cats have the highest measures of genetic variation whereas several breeds have critically low genetic variation, such as Burmese and Birman. Breeds that have been developed more recently from random bred populations, such as Siberians and Munchkins, have high diversity, as well as breeds continually pulled from random bred populations, such as the Manx cats from the Isle of Man. Note: Domestic group represents random bred samples where as Oriental/Toyger is pedigree.
