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

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 7 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 7 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
