Penedo, Stefan Rieder, Tosso LeebRaw phenotypes for individual horses are indicated as black circles. The average values for each genotype class are indicated by red lines. While there is considerable variation in the phenotypic expression, the average proportion of white face area is higher in chestnut horses versus bay horses and it is also higher in horses carrying both the MITFprom1 and the PAX3C70Y allele than in horses carrying only one of the two splashed white alleles (p<0.05, two-sided Welch t-test). The white face areas of all horses and the p-values between all different genotype classes are given in Table S2.
