Qataris subpopulations (Bedouin, Persian-South Asian, African) harbor J2 haplogroup

Rodriguez-Flores et al 2016 in their study about the ancient Eurasian population split sequenced with a median depth of 37× 108 purportedly unrelated individuals who are citizens of the nation of Qatar. 56 of them are of indigenous Bedouin ancestry who are the best representatives of autochthonous Arabs. Genetically most of them could be placed in three distinct clusters: 60 […]


Bekada et al 2015 have published their paper “Genetic Heterogeneity in Algerian Human Populations”. In the present Algerian study only one J2a -M410 was found in North-west Oran1. Combined with earlier studies 8 J2 samples out of 305 total (Y-STR19 haplotypes + major Y-SNPs, S1 Table). By comparison there are 54 J1-M267 samples. IMHO another puzzle piece making early J2 expansion over Northwest Africa to Iberia/Europe unlikely. Other routes seem to be better expansion vectors.
