Phylogenetic tree constructed with 14 Y chromosome markers based on the YCC nomenclature. The Y haplogroups were classified according to the presence/absence of various binary markers. Each haplogroup and the diagnostic markers are indicated in the roots and in the ends of the branches. The DE* (putative D) or NO* (putative O) and HIJK* haplogroups were defined by the absence of the typed SNPs [9, 10]
