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

Cómo interpretar el análisis de mezcla genética
Descubre cómo funcionan las calculadoras de mezcla genética y cómo interpretar los resultados
¿Qué es el análisis de mezcla genética?
El análisis de mezcla genética estima la similitud genética comparando tu ADN con poblaciones de referencia de distintas partes del mundo. Los componentes del modelo representan esas referencias y dependen de los datos y supuestos utilizados.
Esta calculadora utiliza 12 cuidadosamente seleccionadas modern poblaciones como referencias para describir con detalle la similitud genética.
Cómo funciona
- Tu ADN se compara con 12 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Los resultados muestran tu similitud genética con estas poblaciones
- La diversidad del panel de referencia influye en las estimaciones
Cómo interpretar tus resultados
Los resultados muestran porcentajes de similitud genética con estas poblaciones de referencia. Ten presentes estos puntos:
- Los resultados reflejan similitud genética, no ascendencia directa demostrada
- Modern se utilizan como referencias
- Los porcentajes indican contribuciones relativas en el modelo
- Los resultados son estimaciones basadas en los datos de referencia disponibles
