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.
Just like other coat colors and patterns, the brindle color pattern is a genetic trait, caused by a particular combination of genes. There are a handful of different places (loci) along your dogâs DNA strand that determine her color pattern. These are referred to as gene series, and they are labelled by a letter.
