Abstract:

The purpose of this study is to provide more theoretical basis for the research of evolution of bovine and chromosome electrolocalization of some goat′s coat color genes. The homology of chromosomes among cattle, sheep and goat was analyzed using Phylogenetic Computer Tools and Phylip software based on markers located at their autosomes. Partial coat color candidate genes of goat were mapped using the method of comparative genomics and bioinformatics. The results indicated that similarity of homologous chromosomes among these species was 0.000 0-1.000 0. The coat color candidate genes of goat, Myo5a, Brca1, Sox10, Zic2, kit, Snai2, Wnt3a and Tyrp1 were oriented at chromosome 10, 17, 5, 12, 6, 14, 7, and 8,respectively.
