Melanistic Mask – EM Locus The dominant Em allele of MC1R is responsible for the localized distribution of eumelanin on the muzzle that resembles a darkened mask in a pheomelanic (ay) background. The melanistic mask caused by one copy of this allele is only visible on dogs that are fawn or brindle.
Is melanistic mask dominant or recessive?

What is the EE gene in dogs?
The E allele provides the ability to make eumelanin in the coat and is dominant to the e allele (recessive red). Dogs that are EE or Ee can produce dark (black, brown, blue, isabella) hairs, but their distribution will be dependent on the genotypes at the K and A loci.
