The Middle Eastern component was found to be comparable across all North African Jewish and non-Jewish groups, while North African Jewish groups showed increased European and decreased levels of North African (Maghrebi) ancestry [23] with Moroccan and Algerian Jews tending to be genetically closer to Europeans than Djerban Jews. The study found ...
