From: Complete human mtDNA genome sequences from Vietnam and the phylogeography of Mainland Southeast Asia

Diversity and distribution of subhaplogroups B4, B5, and B6a. (a,b) Network of haplogroup B4 complete mtDNA sequences. (c,d) Network of haplogroup B5 and B6a complete mtDNA sequences, color-coded by linguistic affiliation and geographic origin, respectively. (e–g) Spatial frequency distribution maps of haplogroups B4, B5 and B6a in MSEA, respectively: the more intense the color, the higher the frequency in the population. Crosses mark the sampling sites of the 68 MSEA populations included in the analysis (see Table S1 in Online Resource 1).
