Cats

There is also the phenomenon of white toes occurring on otherwise coloured cats. In the York Chocolate breed, there is a particular white displacement in bicoloured individuals. The placement of white maintains the same configuration in all successive generations. This has been termed "Spotting Particolour" and may be due to an allele (variant) of the White Spotting gene. According to this theory, the White Spotting gene appears to have 4 variants: non-spotted, spotted, particolor, and Birman mitted. Spotted is the dominant form and is variable expressed. Non-spotted is the recessive wild-type and produces a coat without white. The hypothetical Birman allele (or Birman mitted) is also variable, but confines the white spotting to the legs and feet. The hypothetical Particolour allele produces an inverted white "V" with the apex in the centre of the forehead and passing through the centres of the eyes plus a white chin, chest, belly, legs and feet are white.
