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

Como interpretar a análise de mistura genética
Descubra como funcionam as calculadoras de mistura genética e como interpretar os resultados
O que é a análise de mistura genética?
A análise de mistura genética estima a semelhança genética comparando o seu DNA com populações de referência de diferentes partes do mundo. Os componentes do modelo representam essas referências e dependem dos dados e pressupostos utilizados.
Esta calculadora utiliza 12 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 12 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Os resultados mostram a sua semelhança genética com estas populações
- A diversidade do painel de referência influencia as estimativas
Como interpretar seus resultados
Os resultados mostram percentagens de similaridade genética com estas populações de referência. Tenha presente estes pontos:
- Os resultados reflectem a semelhança genética, não ascendência directa demonstrada
- Modern se utilizan como referencias
- As percentagens indicam contribuições relativas no modelo
- Os resultados são estimativas baseadas nos dados de referência disponíveis
