a Manhattan plot based on the GWAS results for the presence/absence of white color on the coat. The top variants on chromosome 22, 6 and 2 have p-values of 1.51 × 10−56, 3.73 × 10−53 and 3.26 × 10−15, respectively. b Manhattan plot based on the GWAS results for the proportion of white spotting. The top variants on chromosome 22, 6 and 2 have p-values of 1.83 × 10−79, 1.1 × 10−64 and 1.27 × 10−13, respectively. The red line indicates the genome-wide significance threshold p = 5 × 10−8
