| Abstract: The objective of this work was to identify single nucleotide polymorphisms (SNPs) in resequencing data from MC1R, ASIP, and TYRP1 genes derived from Crioula sheep (Ovis aris) with different coat colors. Polymorphisms in the ASIP (agouti-signaling protein), MC1R (melanocortin 1 receptor), and TRYP1 (tyrosinase-related protein 1) genes were analyzed in 115 sheep from Embrapa’s conservation nucleus of crioula sheep, in Brazil. A total of 7,914 bp were sequenced per animal, and 14 SNPs were identified. Two additional assays were performed to detect duplications and deletions in the ASIP gene. Ninety-five percent of the coat color variation was explained by epistatic interactions observed between specific alleles in the MC1R and ASIP genes. Evidence... |
