Coat Color
Widow's Peak (Discovered in the Afghan Hound and Saluki)

The Widow's peak (Discovered in the Afghan Hound and Saluki) is also known as the Grizzle variant. It is responsible for a blended effect of light and dark hair, with the lower part of the body appearing lighter than the top. Other names for this variant include Eg and Domino, and it is found in the MC1R gene (known as the E locus), and is a rare trait.
