Dodecad Africa 9

Dodecad Africa 9 is an admixture calculator designed to analyze the continental and regional ancestral composition of individuals with African ancestry using nine carefully chosen reference populations. It quantifies proportional ancestry contributions from Europe, Northwest Africa, Southwest Asia, East Africa, Southern Africa, West Africa, and three deep hunter‑gatherer lineages represented by Mbuti, Biaka, and San. The calculator uses allele‑frequency contrasts to highlight both recent and ancient gene flow that shaped modern African genomes. Who it’s for: this tool is intended for people of African descent, family historians, population geneticists, educators, and anyone curious about regional African ancestry. It is particularly useful for users seeking finer resolution inside Africa — distinguishing coastal, interior, and hunter‑gatherer inputs — and for those investigating Eurasian backflow into Africa or intra‑African migrations. Insights you can gain: Dodecad Africa 9 provides proportional estimates that help identify Eurasian admixture (European or Southwest Asian), North African signatures, regional African origins (West, East, Southern), and persistence of deep Pleistocene lineages (Mbuti, Biaka, San). Results can illuminate the genetic echoes of the Bantu expansion, Nilotic movements, trans‑Saharan and Indian Ocean contact, colonial-era mixing, and surviving hunter‑gatherer ancestry. Context and value: Africa has the world’s deepest and most complex genetic structure. By including distinct hunter‑gatherer references and multiple regional African and Eurasian proxies, this calculator captures meaningful contrasts often blurred in broad models. It does not provide precise birthplace or genealogical certificates, but offers a scientifically grounded, interpretable profile that complements historical records and other genetic analyses. Interpretation guidance: outputs are estimates, not definitive labels. Small percentages may reflect ancient shared ance
