The EG allele encodes a coat colour variant called domino in Afghan hounds and grizzle in Salukis and has been found in the Barsoi as well. This pattern is characterized by a pale face with a widows peak above the eyes and appears to be unique to these two old dog breeds. EG is dominant over E and e alleles but recessive to the EM allele. Only dogs possesing at/at genotype at the A locus and ky/ky at the K locus exhibit this phenotype.
