A point is a cat color pattern in which the "points", or extremities, are colored, while the rest of the body is a light tan. The most notable breed with this pattern is the Siamese, but other breeds with this pattern include the Himalayan, Balinese, Birman, Ragdoll, and Tonkinese.
Genetics[]
The genetic basis for point coloration is in the tyrosinase "C" gene, which has 5 alleles: C = full color c = true albino ca = blue-eyed albino cs = Siamese pattern cb = Burmese pattern The full-color gene is dominant to the albino genes, which are dominant to the Siamese and Burmese genes.
Tonkinese[]
The Tonkinese pattern happens when a cat has both a cs and a cb. The result is a "mink" appearance, with dark points and a medium-brown body.
