Eurogenes JTest

Eurogenes JTest analyzes genome-wide autosomal data to estimate ancestry proportions across fourteen reference components specifically tailored to modern European populations. Designed for people with European heritage, population geneticists, and genealogy researchers, it compares a test genome to reference clusters including SOUTH_BALTIC, EAST_EURO, NORTH-CENTRAL_EURO, ATLANTIC, WEST_MED, ASHKENAZIM, EAST_MED, WEST_ASIAN, MIDDLE_EASTERN, SOUTH_ASIAN, EAST_AFRICAN, WEST_AFRICAN, EAST_ASIAN and SIBERIAN. The calculator quantifies the relative contribution of these components to an individual’s genetic makeup and highlights subcontinental affinities — for example Baltic, Atlantic coast, Mediterranean, Eastern European, Caucasus/West Asian — and flags traces of non-European gene flow. Results present percentage breakdowns, ranked population similarities, and contextual notes about historical processes that likely shaped those patterns, from Neolithic farmer expansions and Bronze Age steppe movements to medieval trade, Jewish diasporas, and more recent colonial or overland contacts. The reference set intentionally mixes dense Europe-centric clusters with extra-European groups so users can detect both regional gradients within Europe and signals of outside admixture (e.g., West Asian, Middle Eastern, South Asian, African or East Asian contributions). Eurogenes JTest is valuable because it balances resolution and interpretability: it reveals subtle gradients without overclaiming precision, and pairs numeric outputs with plain-language explanations and confidence guidance to reduce misinterpretation of small percentages. Suitable for modern-era samples (present-day DNA and recently dated material), it’s useful for individuals exploring family history, researchers conducting population comparisons, and enthusiasts generating testable hypotheses about ancestry. Clear visuals, concise summaries, and historically informed commentary make Eurogenes JTest a practical, educati
