Dodecad K12b — Modern 12-way Admixture Calculator
Dodecad K12b is a modern, global admixture calculator that decomposes an individual's genome into twelve ancestral components derived from broad reference populations. It analyzes allele frequency patterns across the genome to estimate proportional ancestry from: Gedrosia, Siberian, Northwest African, Southeast Asian, Atlantic Mediterranean, North European, South Asian, East African, Southwest Asian, East Asian, Caucasus, and Sub-Saharan groups.
Who it's for
- Genetic enthusiasts, genealogists, and curious individuals seeking a clear, comparative view of their deep ancestry
- Researchers and students who need a convenient, standardized 12-component breakdown for population comparisons
What you gain
- A breakdown of ancestry proportions that highlights major continental and regional contributions
- Contextual interpretation: which components typically reflect West Eurasian, African, South Asian, and East Asian heritage
- A starting point for historical inference—migration signals, admixture events, and regional affinities—when combined with archaeological and linguistic evidence
Genetic and historical context
K12b is an allele-frequency based model optimized for modern populations: it captures long-term regional differentiation rather than single recent genealogical events. Components like Gedrosia and Caucasus reflect shared West Asian ancestries, while Atlantic Med and North European resolve diverse European contributions. Asian and African diversity are represented through East Asian, Southeast Asian, Siberian, East African, and Sub-Saharan components.
Why use Dodecad K12b
- Balanced resolution: twelve components provide interpretable regional signals without overfitting
- Global scope: designed for worldwide application, useful for multi-ethnic samples
- Comparative utility: easy to compare individuals, populations, and published datasets
Limitations

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
