Biochemistry of Dog Coat Color. The color of a dogâs coat is determined by relative levels of two pigments: eumelanin, which can be either brown or black, and pheomelanin, which is yellow to orange or red. Both pigments are generated by metabolism of tyrosine. A schematic diagram of the pathway is below. Schematic of the melanin synthesis pathways.
For example, letâs say that there is one gene which determines the color of your hair. That one gene may have many forms, or alleles: black hair, brown hair, auburn hair, red hair, blond hair, etc. You inherit one allele for each gene from your mother and one from your father.
