Fig. 2From: Ancestors’ dietary patterns and environments could drive positive selection in genes involved in micronutrient metabolism—the case of cofactor transportersLinkage disequilibrium plots and haplotype network of SLC24A3 regions in African populations. a Visualization of LD between the genetic variants in SLC24A3 regions bearing signals of positive selection. LD was calculated using r 2 parameter separately in African populations of farmers and hunter-gatherers. Squares shaded according to strength of LD. b Haplotype network analysis of SLC24A3 regions. Each circle represents a haplotype that is color-coded according to the population in which it is present. Circle sizes are proportional to the haplotype frequency and each line corresponds to one mutational stepBack to article page
