North African Ancestral Calculator (by Al Qastalli) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). North African Ancestral Calculator is a free Global25 (G25) ancestry calculator by Al Qastalli. It focuses on North African ancestry: Amazigh, Arab and ancient Maghrebi populations. It models your coordinates with 65 reference populations, including Anatolian Neolithic Farmer, Sub Saharan Africa, Zagrosian Neolithic Farmer, Steppe and North African Hunter Gatherer. Paste your scaled G25 coordinates to get your best-fit ancestry mix, computed directly in your browser. Its reference panel holds about 65 reference populations, grouped mainly as Anatolian Neolithic Farmer, Sub Saharan Africa, Zagrosian Neolithic Farmer, Steppe, North African Hunter Gatherer, Natufian, West Europe Hunter-Gatherer WHG, Caucasus Hunter Gatherer.The panel was built or amended by Al Qastalli.Last updated: March 2026 (version 2026-03).
People who already have their Global25 (G25) coordinates, for example from a raw DNA file converted with our G25 coordinates service, and want to see how a specific reference panel reads them. Different calculators use different panels, so the same person can get different percentages, and comparing several is more informative than trusting one.
Paste your coordinates, choose a run mode and start the calculation. Each result line is a reference population followed by the share of your ancestry it explains, the shares add up to 100%. Very small shares (below roughly 1 to 2%) are usually noise rather than real ancestry. The distance value tells you how well the mixture reproduces your coordinates: the lower, the better, and a high distance means this panel does not describe you well. For example, a result of "Polish 60 / Ukrainian 25 / Lithuanian 15" means your coordinates are best rebuilt from those three populations in those proportions, not that you descend from three separate groups.
