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.

Referenzpopulationen
Die in diesem Rechner als genetische Referenzen verwendeten Populationen
9 Referenzpopulationen
Europe: Represents the genetic component associated with populations from Europe, including various European countries and regions.
Nw Africa (Northwest Africa): Corresponds to genetic contributions from Northwest Africa, encompassing countries like Morocco, Algeria, and Tunisia.
Sw Asia (Southwest Asia): Represents ancestral contributions from the southwestern part of Asia, which includes regions like the Middle East.
E Africa (East Africa): Denotes genetic affiliations with East African populations, such as those found in countries like Ethiopia, Kenya, and Tanzania.
S Africa (Southern Africa): Represents the genetic component associated with Southern African populations, including countries like South Africa, Namibia, and Zimbabwe.
Mbuti: Indigenous hunter-gatherer populations from the rainforests of Central Africa, signifying genetic similarities with them.
W Africa (West Africa): Corresponds to genetic contributions from West African populations, including countries like Nigeria, Ghana, and Senegal.
Biaka: Another indigenous hunter-gatherer group from Central Africa, indicating genetic affinities with them.
San: Indigenous hunter-gatherer populations from Southern Africa, also known as Bushmen or Basarwa, signifying genetic similarities with them.

Was ist eine Admixture-Analyse?
Bei einer Admixture-Analyse wird Ihre genetische Ähnlichkeit geschätzt, indem Ihr DNA mit Referenzpopulationen aus verschiedenen Weltregionen verglichen wird. Die Komponenten des Modells stehen für diese Referenzen und hängen von den zugrunde liegenden Daten und Annahmen ab.
Dieser Rechner nutzt 9 sorgfältig ausgewählte modern Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 9 Referenzpopulationen verglichen
- Modern-Populationen dienen als genetische Referenzen
- Die Ergebnisse zeigen Ihre genetische Ähnlichkeit zu diesen Populationen
- Ein vielfältiges Referenzpanel verbessert die Schätzungen
Ihre Ergebnisse verstehen
Ihre Ergebnisse zeigen Prozentsätze der genetischen Ähnlichkeit zu diesen Referenzpopulationen. Beachten Sie diese Punkte:
- Die Ergebnisse spiegeln genetische Ähnlichkeit wider, nicht nachgewiesene direkte Abstammung
- Modern-Populationen werden als Referenzen verwendet
- Die Prozentsätze geben relative Beiträge im Modell an
- Die Ergebnisse sind Schätzungen auf Basis der verfügbaren Referenzdaten
