Characterization of two selection signals encompassing the genes related to hair growth in TC. a Log₂(θ_π ratios), F_ST, and Tajima’s D values in 10-kb outlier windows overlapping with the FGF5 gene. b Representative Sanger sequence traces of two alleles at the c.-253G > A SNP site in the 5′-UTR of FGF5. c The allele frequency at the c.-253G > A SNP site in the 5′-UTR of FGF5 in five domestic goat breeds (CB, JT, TC, MD, and MN) and Bezoar ibexes. d The predicted premature amino acid sequence caused by the mutant allele ‘A’ at the c.-253G > A SNP site in the 5′-UTR of FGF5. e Log₂(θ_π ratios), F_ST, and Tajima’s D values in 10-kb outlier windows encompassing DSG2, DSG3, and DSG4. f Pairwise LD between the three missense SNPs (chr24: 25,985,493, 25,985,494, and 25,985,569) and other SNPs in the DSG3 gene in TC. Squares in pink or red indicate significant LD between SNP pairs (bright red indicates pairwise D′ = 1). g The haplotype frequencies composed of the seven SNPs showing perfect LD in the five domestic goat breeds (CB, JT, TC, MD, and MN) and Bezoar ibexes
