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.

计算器中用作遗传参考的种群
9 Reference Populations
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.

什么是“混合分析”?
混合分析是用来通过将你的DNA与来自世界各地的参考人群进行比较来估计你的基因祖先的一种方法。 把它看作是创造了你的基因化妆的食谱, 即成分是不同的祖先种群。
此计算器使用 9 仔细选择 modern 作为参考,可以详细分解您的遗传遗产。
如何运作
- 将您的 DNA 与 9 个参考人群进行比较
- 以 Modern 人群作为遗传参考
- 结果显示你的基因与这些种群相似
- 使用不同的参考面板更准确
了解你的成果
您的研究结果将显示与这些参考人群的遗传相似性的百分比。请记住这些要点:
- 结果反映了遗传相似性,而不是直接祖先
- Modern populations are used as references
- 表明相对遗传贡献的百分比
- 结果是根据现有参考数据作出的估计数
