Inheritance of coat colour in the Anatolian Shepherd dog

The predominant colour of the Anatolian Shepherd dog varies from a dark fawn to light red, with a variable black muzzle and face (mask). Evidence is presented that the colour is due to the dominant yellow allele (A ^y) of the agouti locus. Two other frequent colours are white spotting, due to the piebald allele (s ^p), and the chinchilla allele (ch). Two rarer colours are the agouti wolf-grey wild type (A ⁺) and a light fawn with a blue facial mask, due to the dilution allele (d).
