Figure 2. Manhattan plot of association of 658,385 SNPs with the proportion of daughters with ambilateral circumocular pigmentation in 3579 bulls of the Fleckvieh breed.

The chromosomes are separated with alternating colours. Orange and red dots indicate chromosome-wide and genome-wide (P<7.59×10⁻⁸) significantly associated SNPs, respectively. The vertical axis is truncated for P values below -log10(10–41). Twelve identified QTL regions are indicated with arrows and gene identifiers.
