A study found that the Palestinians, like Jordanians, Lebanese, and Syrians have what appears to be Female-Mediated gene flow in the form of Maternal DNA Haplogroups from Sub-Saharan Africa. 15% of the 117 Palestinian individuals tested carried maternal haplogroups that originated in Sub-Saharan Africa. These results are consistent with female migration from eastern Africa into Near Eastern communities within the last few thousand years. There have been many opportunities for such migrations during this period. However, the most likely explanation for the presence of predominantly female lineages of African origin in these areas is that they may trace back to women brought from Africa as part of the Arab slave trade, assimilated into the areas under Arab rule.
