Table 3.

Phenotypic variance explained by the identified autosomal loci significantly associated with hair color. The current estimates are given as the ratio of the genetic variance, V(G), over the phenotypic variance (Vp) and scaled over the population prevalence, V(G)/Vp_L, (estimated in the UKBB cohort, N=133,238), on the right. The estimates of genetic variance explained by known SNPs prior to this study were taken from previous publications. The phenotypes in this table were compared with all other hair colors. Since 80% of the participants reported some shade of brown hair color (dark or light), the heritabilities for these two phenotypes were considered baseline and were not calculated.
