Dodecad Globe 4
Dodecad Globe 4 — Global modern admixture calculator
A scientifically grounded autosomal admixture tool that estimates ancestry proportions across 21 global reference populations. Designed for researchers, genealogists, and curious individuals, it reveals continental and subcontinental components (European, African, Asian, Amerindian) to illuminate migration, contact, and recent admixture—presented clearly and quantitatively.

Dodecad Globe 4 — Modern Global Admixture Explorer
Dodecad Globe 4 is an autosomal admixture calculator optimized for modern, world-wide genetic datasets. It estimates proportional ancestry from 21 reference populations, spanning broad continental groups and fine-grained subregions (European, Asian, African, and Indigenous American components). The calculator analyzes genome-wide SNP data to produce a compositional portrait of an individual's recent and deep ancestry.
Who it's for:
- Researchers and population geneticists seeking a comparative global panel
- Genealogists and curious individuals exploring multi-continental roots
- Anthropologists and historians interpreting migration signatures
What you learn:
- Quantitative ancestry proportions across 21 reference populations (e.g., Northwest European, South Asian, West African, Andean)
- Biogeographic affinities and likely regional signals
- Detection of minor components that reflect historical contact (trade routes, colonization, or recent admixture)
Historical and genetic context: Human populations carry layered signatures of ancient migrations (Out of Africa, Eurasian expansions), regional founder events, and recent movements (colonization, slave trade, intercontinental migration). Dodecad Globe 4 frames your genome against this context, highlighting how continental and subcontinental ancestries combine in modern individuals and populations.
Why it matters:
- Broad, globally balanced reference set captures diversity across continents and Indigenous American subregions
- Useful for hypothesis generation about population history and recent admixture
- Presents results in an interpretable, quantitative format suitable for comparison across samples
Important caveats:
- Results are probabilistic and depend on the chosen reference panel; small component estimates are sensitive to reference composition
- Interpret outputs alongside historical, genealogical, and archaeological evidence for best inference

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 4 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 4 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
