Full global modern and ancient jewish analyze (by Erik Svensson) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). Full global modern and ancient jewish analyze is a free Global25 (G25) ancestry calculator by Erik Svensson. It is built to explore Jewish ancestry, comparing Ashkenazi, Sephardi, Mizrahi and other Jewish communities with ancient and host populations. It models your coordinates with 35 reference populations, including Levant Yehud IBA, Jew Erfurt Medieval High EEF, Jew Erfurt Medieval Levantine, Jew Erfurt Medieval EU and Jew Erfurt Medieval Intermediate. Paste your scaled G25 coordinates to get your best-fit ancestry mix, computed directly in your browser. Its reference panel holds about 35 reference populations, grouped mainly as Levant Yehud IBA, Jew Erfurt Medieval High EEF, Jew Erfurt Medieval Levantine, Jew Erfurt Medieval EU, Jew Erfurt Medieval Intermediate, Jew Medieval Norwich, Jew Ancient Al Andalus Proxy, Jew Ancient Roman Late Antiquity.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.
Everything runs in your browser and nothing you paste is uploaded. Browse all Global25 calculators, or let the free Report Finder tell you which regional report fits your ancestry.
