Eurasia K20
Eurasia K20 — Modern + Ancient admixture snapshot
Quickly quantify genome-wide ancestry against 20 curated modern and ancient components spanning Eurasia, Africa, Oceania and the Americas. Designed for hobbyists, genealogists and researchers, it highlights Steppe, Neolithic farmer, Siberian, East/Southeast Asian, South Asian, Papuan, African and Native American affinities to contextualize both recent and deep ancestry.

Eurasia K20 — Modern + Ancient Admixture Calculator
This calculator estimates an individual's autosomal ancestry proportions against 20 curated reference components spanning modern and ancient Eurasian, African, Oceanian and American diversity. It is built for anyone curious about deep and recent ancestry: hobbyist genetic genealogists, population geneticists, students, and researchers performing broad comparative analyses.
What this analyzes
- Genome-wide autosomal SNP data compared to 20 reference populations (modern and ancient) to produce proportional ancestry estimates.
- Components capture major demographic signals such as Steppe, Near Eastern, European farmer, Siberian, East and Southeast Asian, South Asian, Papuan, Sub‑Saharan African, and Native American affinities.
Reference components (K=20): NE_ASIAN, N_AMERINIDIAN, SSA, EEF, SE_ASIAN1, S_INDIAN, SHG_WHG, S_AMERINDIAN, KHOISAN, SW_ASIAN, KALASH, E_ASIAN, PYGMY, SE_ASIAN2, CAUCASUS_GEDROSIA, PAPUAN, EUROPEAN, YAMNAYA, E_SIBERIAN, W_SIBERIAN
Insights you can gain
- Quantified ancestry fractions that help place an individual along Eurasian clines and detect non‑European, African, Oceanian, or Native American admixture.
- Signals tied to major historical events: Neolithic farmer expansion (EEF), Steppe migrations (Yamnaya), Mesolithic hunter‑gatherer ancestries (SHG/WHG), and deeper Siberian/East Asian links.
- Finer distinctions within Asia (E_SIBERIAN vs. W_SIBERIAN; multiple SE_ASIAN components) and between South Asian and Near Eastern affinities.
Context & value
- Combines modern and ancient reference profiles to illuminate both recent pedigree-level admixture and deeper population history.
- Useful for triangulating hypotheses about regional ancestry, exploring migration scenarios, and augmenting genealogical results from consumer tests.
Limitations
- Results are model-dependent: component labels are proxies for genetic clusters, not fixed ethnic identities. Interpret proportions as population

Was ist eine Admixture-Analyse?
Bei einer Admixture-Analyse wird Ihre genetische Ähnlichkeit geschätzt, indem Ihr DNA mit Referenzpopulationen aus verschiedenen Weltregionen verglichen wird. Die Komponenten des Modells stehen für diese Referenzen und hängen von den zugrunde liegenden Daten und Annahmen ab.
Dieser Rechner nutzt 20 sorgfältig ausgewählte moderne und antike Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 20 Referenzpopulationen verglichen
- Modern und antik-Populationen dienen als genetische Referenzen
- Die Ergebnisse zeigen Ihre genetische Ähnlichkeit zu diesen Populationen
- Ein vielfältiges Referenzpanel verbessert die Schätzungen
Ihre Ergebnisse verstehen
Ihre Ergebnisse zeigen Prozentsätze der genetischen Ähnlichkeit zu diesen Referenzpopulationen. Beachten Sie diese Punkte:
- Die Ergebnisse spiegeln genetische Ähnlichkeit wider, nicht nachgewiesene direkte Abstammung
- Modern und antik-Populationen werden als Referenzen verwendet
- Die Prozentsätze geben relative Beiträge im Modell an
- Die Ergebnisse sind Schätzungen auf Basis der verfügbaren Referenzdaten
