At the top are shown drawings illustrating the seven hair features examined in this study; thick lines connect these features with the candidate genes identified in regions with single-nucleotide polymorphisms (SNPs) reaching genome-wide significant association. At the bottom is shown a composite Manhattan plot displaying all significantly associated SNPs for the hair features examined; the rs number of the SNP with the smallest P value is shown at the top of each association peak.
