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
This is a statist

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
