Figure 4
High resolution phylogenetic network of haplogroups A and E. The diameter of the circles is proportional to the number of individuals sharing the same sequence. The sample number is in black. In case of circles representing two or more samples only the first is reported. The branch length is proportional to the number of SNPs. In blue the number of SNPs for the main branches and for secondary branches longer than 50 SNPs. The known sub-haplogroups are labelled according to the most recent ISOGG nomenclature and represented with darker color. The labels of the main sub-haplogroups are framed in red. On the bottom left of the panel a small representation of the complete phylogenetic tree is reported. The circle indicate the position of the haplogroups in the general tree.
