Sequence variants were discovered by sequencing the three genes in 4 white, 4 black, and 4 brown dromedaries. Sequence positions correspond to dromedary whole genome assembly: GCA_000767585.1 PRJNA234474_Ca_dromedarius_V1.0.; MC1R scaffold ID: NW_011592664.1, ASIP scaffold ID: NW_011591043.1 and TYRP1 scaffold ID: NW_011591511.1; Numbers in columns White, Black, Brown denote the number of animals with the corresponding genotype; ORF, open reading frame; D, deletion; P-value for genotype–phenotype association was determined by contingency analysis in JMP using Chi-square (see Supplementary Figure S2).
