Abstract

In this work, we have analyzed a total of 295 unrelated Berber-speaking men from the northern, center and southern of Morocco, in order to characterize frequency of E1b1b1b-M81 haplogroup and to refine the phylogeny of its subclades: E1b1b1b1-M107, E1b1b1b2-M183 and E1b1b1b2a-M165. For this purpose, we have typed four biallelic polymorphisms: M81, M107, M183 and M165. As results, a large majority of the Berber-speaking male lineages belong to the Y chromosomal E1b1b1b-M81 haplogroup. The frequency ranged from 79.1 to 98.5% in all localities sampled. Then, the E1b1b1b2-M183 was the most dominant subclade in our samples, which ranged from 65.1% to 83.1%. In contrast, the E1b1b1b1-M107 and E1b1b1b2a-M165 subclades weren’t found in our samples. Our results suggest a predominance of E1b1b1b-M81 haplogroup among Moroccan Berber-speaking male with a decreasing gradient from south to north. Then, the most prevalent subclade in this haplogroup was E1b1b1b2-M183 in which difference between these three groups was statistically significant between central and southern groups.
