Genotype of each mouse strain for five pigment associated genes.

For each gene, the wild-type allele is designated by the ‘+’ symbol. The ‘Aw’ allele of the a gene carried by the 129X1/SvJ strain is a distinct variant that has been classified as wild-type for this study. No genotype information was available for the C57BL/KALWRIJ strain. NA indicates an unavailable genotype.对于每个基因，野生型等位基因以符号‘+’表示。129X1/SvJ品系携带的a基因的‘Aw’等位基因属于独特变异体，在本研究中被归类为野生型。C57BL/KALWRIJ品系无可用基因型信息。NA代表基因型不可用。
