Fig. 1

A phylogenetic tree with 23 hierBAPS groups of haplogroup U5 mitogenome sequences. Roman numerals denote the hierBAPS subclades. The hierBAPS subclades were superimposed on a phylogenetic tree, generated using maximum likelihood analysis, to help visualize the phylogenetic relationships of each sequence. The yellow coloring represents the U5a subhaplogroup while the blue coloring represents the U5b subhaplogroup. RSRS is the Reconstructed Sapiens Reference SequenceÂ
