Modern and ancient African analyze (by Erik Svensson) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). Modern and ancient African analyze is a free Global25 (G25) ancestry calculator by Erik Svensson. It focuses on African ancestry, from Central and Southern African hunter-gatherers to West African, Bantu and East African populations. It models your coordinates with 20 reference populations, including Ethiopia 4500BP Mota, Malawi 8100BP Hora, South Africa 2000BP BallitoBay, Kenya EarlyPastoral 3000BP and Tanzania Luxmanda 3100BP. Paste your scaled G25 coordinates to get your best-fit ancestry mix, computed directly in your browser. Its reference panel holds about 20 reference populations, grouped mainly as Ethiopia 4500BP Mota, Malawi 8100BP Hora, South Africa 2000BP BallitoBay, Kenya EarlyPastoral 3000BP, Tanzania Luxmanda 3100BP, Yoruba, Mandenka, Gambian.The panel was built or amended by Erik Svensson.Last updated: October 2026.
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.
