Abstract: Canines were domesticated approximately 10 000 years ago, The various environmental conditions and selective breeding resulted in aboudant diversity of coat colors in domestic canines. Many canine coat colors are affected by melanocortin 1 receptorMC1R. MC1R genes are homologous among different species. This article reviews the studies on MC1R polymorphism in the domestic canine. We also constructed a phylogenetic tree of MC1R genes by comparing the canine gene with those from nine representative mammalian species. Resulte show the gene phylogenetic tree accorded with Taxonomy of the ten mammals in the main.
