This mask is also known as a melanistic mask. This allele acts similarly to the E allele in that it causes a black-based coat. Because it is dominant, a dog only needs one copy of the Em allele to express this trait. In solid, black dogs with a copy of the Em allele, the mask is hidden.
Is melanistic mask dominant or recessive?

What is the melanistic mask allele?
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.
What does recessive black mean?
The a allele is sometimes referred to as the recessive black gene. Because this allele is the most recessive, for a dog to express this phenotype he must have two copies of the a allele and be n/n for Ay, aw, and at. A recessive black dog will always pass on the a allele to all offspring.
What are some recessive colors for dogs?
Recessive red dog coat color is recessive in its own series, but dominant over other loci. Dominant black, sable, tan points, wolf grey, merle, and any other pattern with black in it will be turned to solid red by the recessive red gene. This is the main danger of the recessive red dog coat color gene, it masks a lot.
