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.

Distribution of Y haplotype E-M81 E1b1b1b in North Africa, West Asia and Europe. E1b1b1b1 (E-M81), formerly E1b1b1b, E3b1b, and E3b2, is the most common Y chromosome haplogroup in Morocco, dominated by its subclade E-M183. It is thought to have originated in North Africa 14,200 years ago. [32]
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.
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 ...
A map of the locations of genetic samples of several African populations (left) and principal components 1 and 2 of the data superimposed on the map (right). The principal coordinate plane has been rotated 16.11° to align with the map. It corresponds to the east–west and north–south distributions of the populations. [16]
