Phylogenetic tree of new haplogroup M lineages detected in this study and surrounding populations. All SNPs detected are indicated (disregarding cytosine insertions after nps 16193, 309 and 315). Haplogroups M61 and M73 are depicted to show possible phylogenetic relations. Haplogroups according to , release 8. Sequenced range: full mtDNA CR and optional codR covering either (a) all SNPs, (b) most SNPs - for asterisked samples or (c) no SNPs - for underlined samples. For details, see Additional file 4.
