Dodecad Africa 9
Dodecad Africa 9 estimates ancestry proportions for individuals of African descent using nine reference groups — including regional African sources (W, E, S, NW), hunter‑gatherer lineages (Mbuti, Biaka, San), and Eurasian inputs (Europe, SW Asia). It offers a clear, modern view of recent and ancient admixture to aid personal genealogy and population research, with transparency about limitations.

Dodecad Africa 9 — Modern African Admixture Calculator
This calculator estimates the proportional ancestry of individuals with African roots by comparing genotype data to nine curated reference populations. It quantifies contributions from continental and deep African lineages alongside Eurasian inputs to reveal the mosaic of recent and ancient gene flow affecting modern Africans.
What it analyzes
- Genome-wide autosomal ancestry proportions across nine reference groups: Europe, Nw Africa (Northwest Africa), Sw Asia (Southwest Asia), E Africa (East Africa), S Africa (Southern Africa), Mbuti, W Africa (West Africa), Biaka, San.
- Relative shares of hunter‑gatherer lineages (Mbuti, Biaka, San), regional African sources, and non‑African admixture (Europe, NW Africa, SW Asia).
Who it’s for
- Individuals of African ancestry (continental and diaspora) seeking fine-grained regional breakdowns.
- Geneticists, anthropologists, and genealogists exploring population structure, migration, and admixture in modern African contexts.
Insights you can gain
- Proportional ancestry estimates that illuminate recent historical events (trans-Saharan and Indian Ocean contacts, Eurasian backflow) and deeper prehistory (hunter‑gatherer persistence and Bantu-associated spread).
- Distinction between Western, Eastern, Southern and Northwest African signals and identification of Eurasian components.
Historical and genetic context Africa carries deep genetic structure shaped by ancient hunter‑gatherers (San, Mbuti, Biaka), migrations such as the Bantu expansion, and later Eurasian contacts. This calculator provides context by partitioning these influences into interpretable components.
Why it’s valuable
- Offers a balanced, accessible synthesis of complex ancestry into nine meaningful components for modern users.
- Useful for personal ancestry exploration and population-level studies.

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
