Fig. 2: Manhattan plots of hair colour meta-analyses based on logistic mixed models.
From: A large Canadian cohort provides insights into the genetic architecture of human hair colour

a Blonde vs. brown + black hair colour (n = 12,398 individuals). b Brown vs. black hair colour (n = 10,990 individuals). c Red vs. brown + black hair colour (n = 10,450 individuals). The continuous black line denotes the genome-wide significant threshold (p = 1.66e-8). Markers in red are genome-wide significant. The Y-axis has been limited to truncate strong signals of association. The full figure is available as Supplementary Fig. 8.
