Dodecad K7b
Dodecad K7b — Global 7-component admixture
A concise, modern admixture calculator that breaks a genome into seven broad ancestral components using worldwide reference populations (South Asian, West Asian, Siberian, African, Southern, Atlantic_Baltic, East Asian, Asian, African, European). Ideal for genealogists, students, and researchers seeking a rapid, interpretable global ancestry snapshot and a starting point for deeper analyses.

Dodecad K7b — Modern global admixture calculator
The Dodecad K7b calculator decomposes a DNA sample into seven broad ancestral components using a curated set of modern reference populations from across the world. It provides a clear, interpretable overview of major continental and subcontinental ancestry in a contemporary framework, suitable for global comparisons and initial hypothesis generation.
What this calculator analyzes
- Genome-wide SNP genotype data summarized into seven ancestry components using model-based clustering (ADMIXTURE-style inference).
- Affinities to the provided reference groups: South Asian, West Asian, Siberian, African, Southern, Atlantic_Baltic, East Asian, Asian, African, European.
- Relative signals of recent admixture versus deeper shared ancestry across global populations.
Who it's designed for
- Genealogists and ancestry enthusiasts wanting a straightforward global ancestry snapshot.
- Students and researchers exploring broad-scale population structure and comparative patterns.
- Anyone curious how their genome aligns with major modern population clusters.
Insights you can gain
- Percentage breakdown across broad ancestral clusters that reflect major geographic ancestries.
- Which reference groups your genome most closely resembles and where mixture signals are strongest.
- A baseline for interpreting migration history and contact events suggested by your admixture profile.
Historical and genetic context Human genetic variation is shaped by millennia of migration, isolation, and admixture. K7b captures broad components that often correlate with large geographic and historical groups (e.g., South Asian, West Asian, East Asian, African, European). These components are statistical constructs: informative for comparison but not precise proxies for cultural or ethnic identity. Note that similar labels (e.g., two "African" entries) can reflect distinct reference clusters or sampling sets.

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
