There are three possible genetic combinations for the simple recessive red coat color gene that any purebred Alaskan Malamute can carry and exhibit. 1. The first genetic possibility is your dog does not carry the genetic coding for the red coat color expression, which means that your dog has not received the red coat color gene from either of its parents. Therefore he or she is homozygous for not carrying the red coat color gene. 2. The second genetic possibility is your dog carries the genetic coding for the red coat color expression but does not physically exhibit red coat color, which means your dog has received the red coat color gene from only one of its parents, not both! Therefore he or she is heterozygous for the red coat color gene. 3. The third genetic possibility is your dog carries the genetic coding for the red coat color expression an physically exhibits red coat color, which means your dog has received the red coat color gene from both of its parent. Therefore he or she is homozygous for the red coat color gene.

The
gene that controls the red coat color expression in the Alaskan Malamute
is called a simple recessive gene. In a simple recessive gene
there are only two expressions for a particular trait ( Ex. Red Coat
Color ). A dog receives the expression for red coat color from its
father or from its mother or from both its father and its mother.
