The genetic history of North Africa encompasses the genetic history of the people of North Africa.The most important source of gene flow to North Africa from the Neolithic Era onwards was from Western Asia, while the Sahara desert to the south and the Mediterranean Sea to the north were also important barriers to gene flow from sub-Saharan Africa and parts of Europe in prehistory.

West Africans (e.g., Mende of Sierra Leone), bearing the Senegal sickle cell haplotype, [112] [97] may have migrated into Mauritania (77% modern rate of occurrence) and Senegal (100%); they may also have migrated across the Sahara, into North Africa, and from North Africa, into Southern Europe, Turkey, and a region near northern Iraq and ...
E-M215 or E1b1b, formerly known as E3b, is a major human Y-chromosome DNA haplogroup.E-M215 has two basal branches, E-M35 and E-M281. E-M35 is primarily distributed in North Africa and the Horn of Africa, and occurs at moderate frequencies in the Middle East, Europe, and Southern Africa.
Though Northwest Africa has experienced gene flow from the surrounding regions, it has also undergone long periods of genetic isolation in some parts. This has allowed distinctive genetic markers to evolve in some Maghrebi populations, especially in certain isolated Berber-speaking groups. The population of Morocco is genetically heterogenous. [2]
On the other hand, haplogroup E-M215 (E1b1b) is distributed in high frequencies throughout North Africa, Western Asia, East Africa and Europe. Haplogroup E-Z827 was found in Natufian samples (E-Z830+) dated to 10,000 ybp from Palestine, and is commonly found throughout West Asia, North Africa, Europe and Ethiopia.
Gene flow is the transfer of alleles from one population to another population through immigration of individuals. In population genetics, gene flow (also known as migration and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent ...
