Dodecad World 9
Dodecad World 9 gives a clear, modern breakdown of autosomal ancestry using nine global reference components (Amerindian, East Asian, African, Atlantic Baltic, Australasian, Siberian, Caucasus Gedrosia, Southern, South Asian). Ideal for researchers and enthusiasts, it reveals broad migrations and admixture patterns worldwide, offering an intuitive comparative framework while encouraging careful, contextual interpretation.

Dodecad World 9 — Modern global admixture calculator
This calculator evaluates genome-wide autosomal variation and breaks an individual's ancestry into proportions of nine modelled components: Amerindian, East Asian, African, Atlantic Baltic, Australasian, Siberian, Caucasus Gedrosia, Southern, and South Asian. It is a supervised modern-era implementation of the Dodecad-style framework, built to compare personal or population genotypes against globally representative reference clusters.
Who it's for
- Researchers, genetic genealogy enthusiasts, and educators who want a clear, comparative view of major ancestral influences worldwide.
- Individuals seeking context for genetic ancestry beyond single-population labels.
What it analyzes and the insights you gain
- Estimates relative ancestral proportions derived from nine broad reference clusters.
- Reveals mixtures consistent with major prehistoric and historic migrations (e.g., Eurasian steppe fronts, Austronesian expansions, Out-of-Africa dispersals, and Native American founder events).
- Highlights affinities to regional reference sets (useful for tracing multi-continental admixture and recent colonial-era gene flow).
- Offers a compact, interpretable snapshot that complements deeper haplogroup or local-ancestry analyses.
Historical and genetic context
The nine components are anchored in populations that reflect deep and recent population structure across the globe. They do not represent discrete ‘‘pure’’ peoples but model signals left by migrations, isolations, and founder events. Interpreting components together provides a narrative of ancestral contributions rather than definitive ethnographic labels.
Why this calculator is valuable
- Provides an intuitive, reproducible framework for comparing individuals and populations worldwide.
- Useful for spotting broad-scale admixture, assessing regional ancestry balance, and generating hypotheses for further study.
- Designed for clarity: actionable ou

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 9 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 9 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
