For the February issue of DNA Tribes Digest, the article reports on the genetic contribution of North African populations using autosomal STR and autosomal SNP analyses. The study tested 6 North African populations in which all the populations tested showed admixture with their neighboring populations; due to recent, and ancient migrations. While the study remains very simple in nature the results revealed what has been shown about the populations in North Africa in other various studies. In this particular study the North Africans tested had a 20% average of admixture from Sub-Saharan Africa (13.3% west African, 8.5% east African) based on SNP testing.
“Results for both autosomal SNP and autosomal STR markers indicated North African genetic links with populations of the Middle East, Europe, and Sub-Saharan Africa (summarized in Table 3). Differences between results (SNP and STR) express the separate reference datasets available for each type of marker. At present, STR data incorporate a larger global database of populations, which allows for a more detailed analysis of regional admixture components. However, results for both types of marker identified similar geographical links between North Africa and neighboring world regions. In both cases, results identified a primary Middle Eastern component and a secondary European and Sub-Saharan African components. These genetic links might express North Africa’s periodic links with Arab and Phoenician cultures attested in historical sources, as well as more ancient contacts attested in the archaeological record.”
