Abstract
anis lupus familiaris is one of the most beloved pet species with hundreds of world-wide recognized
breeds, which can be differentiated from each other by specific morphological, behavioral and adoptive
traits. Morphological characteristics of dog breeds get more attention which can be defined mostly by
coat color and its texture, and considered to be incredibly lucrative traits in this valued species. Although
the genetic foundation of coat color has been well stated in the literature, but still very little is known about the
growth pattern, hair length and curly coat trait genes. Skin pigmentation is determined by eumelanin and
pheomelanin switching phenomenon which is under the control of Melanocortin 1 Receptor and Agouti Signaling
Protein genes. Genetic variations in the genes involved in pigmentation pathway provide basic understanding of
melanocortin physiology and evolutionary adaptation of this trait. So in this review, we highlighted, gathered and
comprehend the genetic mutations, associated and likely to be associated variants in the genes involved in the
coat color and texture trait along with their phenotypes. Moreover, genetic diversity of other associated genes
were also pointed out to understand this phenomena in detail along with their genotypes for better understanding
the expression and mode of inheritance of this trait for describing dog breeds with more accuracy.
