We genotyped a total of 389 males from Somalia, Sub-Saharan Western Africa, Turkey, and Iraq by a PCR based assay with co-amplification of 25 DNA-fragments and detection of 35 Y chromosome biallelic markers with the single base primer extension technique. A total of 19 different haplogroups were identified. In Somalis, 14 haplogroups were identified. The haplogroup E3b1*(xE3b1b) was found in 77.2 % of the male Somali population, in 6.3 % of Iraqi males and in 1.7 % of male Turks whereas E3b1* was not found in Sub-Saharan Western African males. The frequency of haplogroup E3b1*(xE3b1b) in Somali males is the highest observed in any populations to date, and we suggest that the Somali male population is the origin of this haplogroup. Furthermore, the results are in agreement with a gene flow from Eastern to Northern Africa from a homeland in Somalia. In Somalis, 13.4 % of the males carried J or K haplogroups, which are found relatively frequent in e.g. Iraqis, Turks, and other Arab and Asian populations. This might reflects the historical findings of foreign trading posts at the Somali Gulf of Aden from the 7th century. The distribution of haplogroups will be compared to those in Western African population.
