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.

关于此计算器
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

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 12 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 12 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
