关于此计算器
Global Ancestry K23 2023 is a modern, high-resolution admixture calculator (K = 23) that analyzes autosomal genotype data to estimate the proportion of ancestral components drawn from a worldwide set of reference populations. It is built to identify continental- and subcontinental-level ancestry signals and to help users translate their DNA into geographic and historical context.
What this calculator analyzes
- Percent contributions of 23 reference populations across Africa, Europe, Asia, Oceania and the Americas
- Broad and fine-scale ancestry signals that reflect recent and ancient admixture
- Autosomal patterns that represent the combined inheritance from all ancestral lines
Who this is designed for
- Consumers exploring personal ancestry and ancestry enthusiasts
- Genealogists and adoptees seeking biogeographic clues
- Researchers and students who need a compact K=23 reference for comparative analyses
Insights you can gain
- A proportional breakdown of likely ancestral sources (e.g., West African, Near Eastern, South Asian, Melanesian, Native American)
- Clues about past migrations and contact zones (e.g., Bantu expansions, Eurasian steppe movements, colonial-era admixture, Austronesian dispersals)
- A clearer picture of multi-continental heritage and unexpected minor components
Reference populations include: Benin Togo; Africa Southeastern Bantu; Cameroon Congo; Mali; Senegal; Africa North; Ivory Coast Ghana; Nigeria; Caucasus; Asia Central; Asia South; Near East; Asia East; Europe East; Finland Northwest Russia; Europe West; Iberian Peninsula; Great Britain; Italy Greece; Ireland; Scandinavia; Melanesia; Native American.
Historical and genetic context
- By comparing an individual to geographically and linguistically informed reference groups, the calculator frames ancestry in terms of major demographic events — migrations, trade routes, colonization, and long-term regional continuity.
Why this calculator is valuable
- Offers a balanced, interpretable

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 23 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 23 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
