Fig. 1From: Ancient pathogen-driven adaptation triggers increased susceptibility to non-celiac wheat sensitivity in present-day European populationsMedian-joining network of haplotypes made up of SNPs unusually differentiated among continental population clusters and showing high LD (r 2 ≥ 0.95). AFR are displayed in blue, EAS in green, EUR in red, and NCWS in black. Nodes are proportional to haplotype frequencies, while branch lengths are proportional to the number of variants that occurred in the sequencesBack to article page
