A, Phylogeny of Y-chromosomal haplogroups. The name of each haplogroup is shown at the tip of the lineage (1) according to Underhill et al. () and (2) according to the (). The polymorphisms screened in this study are shown along the branches. Lineage colors correspond to the haplogroup cluster colors of ). Lineages shown by dashed lines were not observed in any of the populations discussed. Haplogroups observed in our samples are shown in boldface. The § symbol denotes 12f2a. B, Frequency distribution of Y haplogroup clusters in African, Middle Eastern, and European samples. Populations include the samples from , as well as Moroccan Arabs (M-Ara), North Central Moroccan Berbers (NM-Ber), Saharawis (Sah), South Moroccan Berbers (SM-Ber) (Bosch et al. ); Sudanese (Sud), Ethiopians (Eth), Europeans (Europe), Malians (Mali), Central Africans (C-Afr), South Africans (S-Afr), Khoisan (Khoi), Middle Easterners (Mid-East) (Underhill et al. ); Ethiopian Jews (Eth-J), Mossi (Mossi), Rimaibe (Rim), Fali (Fali), Ouldeme (Ould), Bamileke (Bamil), and Ewondo (Ewo) (Cruciani et al. ).
