Haplotype analysis of the genomic region encompassing EDAR. Haplotype bifurcation diagram for the genomic region previously identified as being subjected to a selective sweep (see text). The location of known genes in the region is also shown. As described in the text, we selected a core containing the putatively selected 370Val/Ala variant (dark blue circle). The four SNPs that correlate with helminth diversity are represented as light blue circles.
