Phylogeny of the haplogroup E1b1 without (A) and with (B) the SNPs phylogenetically characterized in this study (in red).
A “by lineage” nomenclature system [21] was used to name the haplogroups. For the sake of clarity, the internal structure of haplogroups E-M191 (six sub-haplogroups), E-M78 (11 sub-haplogroups) and E-M81 (3 sub-haplogroups) is not shown. Paragroups E1b1*, E1b1a* and E1b1b* were never observed in our data set (more than 2,000 African Y chromosomes, data not shown). Note that the mutations M154 and M281 have been repositioned (B) with respect to the previously published phylogeny (A); however, the possibility that M154 and M281 are recurrent mutations cannot be excluded. The positions of the mutations M116.2, P268, P269, M84 and M290 in relation to the newly characterized mutations have not been resolved because of the lack of positive control DNAs.
