In this study we addressed the problematics of Arab migration into Africa by the analyses of mutations associated with lactase persistence and surrounding haplotypes defined by SNP polymorphisms. We also investigated relative proportions of sub-Saharan and Eurasian ancestry by mitochondrial DNA of the same samples. We found that the spread of specifically Arabic mutation -13,915*G chronologically corresponds with the historically documented migrations of the Arabic tribes from Arabian Peninsula to Africa. We suggest also that higher frequency of the L-type mitochondrial haplogroups in African Arabs who entered Africa earlier is caused by admixture with sub-Saharan populations.
