HGDP K12
HGDP K12 estimates your genetic ancestry using a 12‑component model built on HGDP reference populations. It delivers proportional ancestry signals tied to global groups (West/East Africa, Near East, South/Central/Southeast Asia, East Asia, Europe, the Americas, Oceania), useful for researchers, genealogists, and curious individuals seeking accessible, contextualized insight into population history and admixture.

Sobre esta calculadora
The HGDP K12 calculator estimates an individual’s genetic ancestry by comparing their genotype to a curated set of global reference populations derived from the Human Genome Diversity Project (HGDP). Using a 12-component clustering model tailored for modern populations, it quantifies proportional ancestry signals tied to geographically and historically meaningful groups — for example Gambian and Esan (West Africa), Luhya (East Africa), Bedouin (Near East), Irula (South India), Kalash (Central/South Asia), Dai and Japanese (East Asia), Finn (Northern Europe), Karitiana (Native American) and Papuan (Oceania) — plus broad “African (Continent)” representation. The calculator is designed for a worldwide audience: geneticists, population historians, genealogy enthusiasts, students, and curious individuals who want a clearer picture of deep and recent biogeographic ancestry.
Outputs are proportional estimates that highlight major ancestral components in a person’s genome and show how those components map onto historical migrations, population structure, and regional admixture. Users gain insight into continental and subcontinental affinities, detect traces of ancient gene flow (e.g., Eurasian–African exchanges), and compare personal results to known population signatures. The tool contextualizes findings with plain-language explanations so both technical and nontechnical users can interpret results responsibly.
Like all admixture tools, the HGDP K12 model provides probabilistic estimates rather than definitive “labels.” Results depend on the chosen reference set and model assumptions; shared ancestry, recent admixture, genetic drift, and limited reference sampling can blur component boundaries. Despite these limits, this calculator is valuable because it combines a well-documented HGDP reference framework with an intuitive K=12 breakdown, making it useful for exploratory research, teaching, or personal discovery. It helps translate complex population genetics into action

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 12 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 12 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
