Dodecad K12a — Global 12-component admixture profile
A clear, modern autosomal admixture calculator that breaks your DNA into 12 ancestral components (Mediterranean, Far Asian, Siberian, North European, South Asian, West African, Caucasus, Gedrosia, East African, Southwest Asian, Southeast Asian, Northwest African). Ideal for researchers and curious users worldwide seeking a high-level, comparative snapshot of genetic ancestry and historical population affinities. Model-based and interpreta

Dodecad K12a — Modern global admixture calculator
This calculator decomposes an individual's autosomal DNA into 12 modeled ancestral components calibrated against modern and ancient reference populations. It is designed for anyone worldwide — hobbyist genealogists, students of population genetics, and professional researchers — who wants a digestible, comparative view of genetic ancestry across broad Eurasian and African axes.
What it analyzes:
- Proportional ancestry signals assigned to 12 components: Mediterranean, Far Asian, Siberian, North European, South Asian, West African, Caucasus, Gedrosia, East African, Southwest Asian, Southeast Asian, Northwest African.
- Patterns that reflect deep population structure, recent admixture, and shared drift with those reference clusters.
Insights you can gain:
- A high-level portrait of how much your genome aligns with major Eurasian and African population clusters.
- Clues about historical migrations and contacts (e.g., Mediterranean and Caucasus links, steppe- or Siberian-related ancestries, African and South Asian connections).
- Comparative context: how your profile differs from or resembles regional averages.
Historical and genetic context:
- These components summarize millennia of migrations — Neolithic farmers, Bronze Age steppe movements, Saharan and Bantu dispersals, Indian Ocean trade, and East/ Southeast Asian expansions — compressed into modern reference signals like Gedrosia (Iranian plateau/South Asian-related) or Northwest African (Maghrebi influence).
Why it’s valuable:
- Offers a clear, reproducible snapshot useful for exploratory research and personal discovery.
- Complements genealogical records by revealing broad ancestral affinities that documents cannot show.
Limitations:
- Components are model-based approximations, not precise ethnic labels; results depend on reference choices and algorithmic assumptions.
Use Dodecad K12a as a robust, interpretable guide to your global genetic h

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 12 sorgfältig ausgewählte modern Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 12 Referenzpopulationen verglichen
- Modern-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-Populationen werden als Referenzen verwendet
- Die Prozentsätze geben relative Beiträge im Modell an
- Die Ergebnisse sind Schätzungen auf Basis der verfügbaren Referenzdaten
