Figure 1.
Manhattan plot of the inverse variance meta-analysis for association with hair color of the 23andMe and UKBB cohorts (meta-analysis N=290,891). The unadjusted significance of association (y-axis) for each SNP on different chromosomes is shown in alternating navy and green along the x-axis with polymorphisms reaching significance at GWAS level (p<5x10-08) depicted in red. The values on the y-axis were truncated at p=10-500.
