Dodecad Eurasia 7
Dodecad Eurasia 7 provides a clear seven-way decomposition of autosomal ancestry for modern-era samples. Comparing your genotype to seven reference populations (Sub_Saharan, West_Asian, Atlantic_Baltic, East_Asian, Southern, South_Asian, Siberian), it returns percentage estimates of major Eurasian and adjacent ancestries—ideal for genetic genealogists, researchers, and curious users seeking a high-level, interpretable admixture snapshot.

Dodecad Eurasia 7 — Modern-era admixture calculator
This calculator estimates an individual's autosomal ancestry proportions using a seven-component model designed to capture broad continental and regional variation across Eurasia and surrounding regions. It compares a tested genotype to seven reference populations: Sub_Saharan, West_Asian, Atlantic_Baltic, East_Asian, Southern, South_Asian, and Siberian, returning interpretable percentage contributions that reflect recent and deep shared ancestry.
Who it's for
- Genetic genealogists seeking clearer regional breakdowns beyond continental labels
- Population geneticists and students exploring contemporary Eurasian admixture patterns
- Curious users worldwide who want a high-level snapshot of ancestral components
What you gain
- A concise, seven-way decomposition of autosomal ancestry expressed as percentages
- A sense of major genetic influences (e.g., West Asian vs. Atlantic-Baltic) relevant to Eurasian histories
- Comparative context for interpreting heritage in light of migration, admixture, and population structure
Historical and genetic context
This model is rooted in modern population-genetics practice: reducing complex variation into major axes that reflect historical migrations and long-term isolation. Components like Atlantic_Baltic and West_Asian capture northwest and southwest Eurasian affinities respectively, while East_Asian, South_Asian, and Siberian reflect distinct eastern and central Asian ancestries. Sub_Saharan and Southern provide crucial contrast for African and Near/Mediterranean signals. The result is not a postcode of ancestry but a statistical portrait of genetic affinities shaped by millennia of movement.
Why use it
- Fast, intuitive overview of where genetic signal clusters across Eurasia
- Useful starting point for deeper analysis with finer-scale tools or historical records
- Designed for global samples; robust to a wide range of background

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 7 cuidadosamente seleccionadas modern poblaciones como referencias para describir con detalle la similitud genética.
Cómo funciona
- Tu ADN se compara con 7 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
