Fig. 4From: Rare intronic variants of TCF7L2 arising by selective sweeps in an indigenous population from MexicoNeighborNet. Network analysis was based on 6061 mutations in the TCF7L2 gene identified from the samples of the 1000 Genomes Project. The dashed red circles indicate the reticulations between the nodes. The letters a, b and c are clusters with phylogenetic coherence. The scale is located at the bottom of the network and shows their substitutions by siteBack to article page
