Language note
The percentages and regional labels in these visualisations describe DNA sequence similarity to reference populations, not fixed proportions of ancestry. Following Kampourakis & Peterson (Genetics, 2023), the term “admixture” has been avoided throughout. What these calculators measure is how closely segments of your DNA resemble segments found in defined reference groups — a statistical similarity score, not a genealogical fraction. All human populations are genetically continuous; the reference categories are analytical tools, not biological essences. Results vary across calculators because each uses different reference panels and mathematical methods. Consistency across multiple independent analyses strengthens confidence that a pattern is real.

Circle size reflects strength of DNA sequence similarity to each reference population group. Percentages are similarity scores, not fixed ancestry fractions. Kampourakis & Peterson, Genetics 2023.

North Africa
23.98%
Morocco, Algeria, Libya. Present in every similarity Mixed Mode combination at ~35–37%. The most substantial non-West-African signal.
Algeria
8 of Top 20
Most frequently appearing North African population in Oracle Mixed Mode results. Strongest specific country-level signal.
Libya
Oracle-4 Dom.
Present in virtually every 4-population Oracle combination. Points toward the central Saharan corridor — the main prehistoric trans-Saharan migration route.
Morocco (Southern)
Oracle #1–2
First Oracle 2-population model: 50% Brong + 50% Morocco-S. Points to Berber and Amazigh Saharan genetic similarity entering from the Atlantic corridor.
Fulani Corridor
Dist. 14.18
Closest single-pop match — more than double any other population. Likely the carrier of the entire North African component via millennia of trans-Saharan contact.
Sephardic Jewish
Trace
Detected across multiple GEDmatch calculators. Enters most likely through the North African Berber component — Sephardic communities established across the Maghreb after 1492.
The North African component at 23.98% is substantial — not a trace — and points consistently toward Algeria, Morocco, and Libya across every Oracle model. The Fulani Corridor is the most likely carrier of this genetic similarity, as the Fulani carry ancient North African Berber DNA sequence similarity embedded in their genome from millennia of trans-Saharan contact and migration. This single ancestral thread likely explains the North African, East African, Mali, and Mediterranean signals as a unified Sahelian story rather than separate discrete lineages.
