The genetics of coat color in dogs (Canis lupus familiaris) is a complex area of study, influenced by multiple interacting genes that produce a wide variety of pigmentation patterns. This article explores the hereditary mechanisms underlying coat color variation, focusing on key genes such as MC1R, ASIP, TYRP1, and CBD103. The molecular pathways involved in melanin production, the inheritance patterns of different colors, and how selective breeding has shaped phenotypic diversity among breeds are discussed. Additionally, the canine karyotype and graphical representations of gene interactions are mentioned. Understanding these genetic principles is important for breeders, veterinarians, geneticists, and the general public seeking to predict and manage coat color outcomes in dogs.
