Abstract
The study of the genetic origins and history of Bedouin populations is important both for questions relating to early Arab ancestry and for understanding the settlement of the Arabian Peninsula and Persian Gulf. There is historical agreement that Arab and Bedouin tribal populations share a common paternal ancestor of either Adnan or Qahtan (Joktan). To investigate the origin of paternal lineages of Bedouin populations, 153 Y chromosomes representing six tribes (three Adnani, three Qahtani (Joktani)) were analyzed hierarchically with a set of 97 Single-Nucleotide Polymorphic (SNP) markers and a 17 Y-STR multiplex. 83% of the Y chromosomes belong to Haplogroup J and the rest are distributed among R, G and E. Our Y-STR results show that diversities are generally low within the six Bedouin tribes, possibly reflecting genetic drift. Based on both the Y-chromosomal haplogroups and results of YSTR analysis, we observed clustering of the Bedouin populations with other Arabs, but statistically-significant genetic differentiation between several of the six populations.
