A, The single mutation of KIT-exon13 in cashmere goats with different coat color. (I) Sequencing of KIT-exon13 in dominant white goat. (II) Sequencing of KIT-exon13 in dominant black goat. (III) Case showing nt 491 A→G missense mutation in white and black goat; B, Alignment of KIT-exon13 amino acid sequence prediction of cashmere goats with other mammals; C, The prediction of secondary structure in white cashmere goat and black cashmere goat. (I) The prediction of goat KIT-exon13 amio acid at the hydrophobic and the secondary structure. The unit of abscissa is amino acids digits and the ordinate is the value of the hydrophilic and hydrophbic balance(HLB). (II) The prediction of base secondary structure in goats. (III) Phylogenetic tree of KIT-exon13 gene of goats with different coat color.
