Global Ancestry K23 — Modern, worldwide admixture calculator
Global Ancestry K23 estimates the proportional ancestry of an individual using 23 modeled components derived from 22 geographically and historically informed reference populations. It is built to detect fine-grained regional signatures across Eurasia, Africa, the Americas, and Oceania in the context of modern human population structure.
What this calculator analyzes
- Genome-wide allele frequency patterns to infer percentage contributions from 22 reference clusters (Anatolian, Baltic, Central-Europe, East-Balkan, East-Med, Eastern-European, Finnish, North-West-European, South-Central-Europe, West-Balkan, West-Med, East-African, North-African, West-African, Central-Asian, East-Asian, South-Asian, South-East-Asian, South-Caucasus, West-Asian, Siberian-Central-Amerindian, South-Amerindian).
- Signals of recent and deep ancestry, distinguishing continental and sub-continental components.
Who it’s designed for
- Genealogy enthusiasts seeking regional breakdowns.
- Researchers and students exploring recent population structure and admixture.
- Individuals curious about how historical migrations shaped their genome across Eurasia, Africa, and the Americas.
Insights you can gain
- Percentage estimates of ancestral contributions from specific historical regions.
- Detection of mixed heritage (e.g., Eurasian–African–Amerindian admixture) and likely geographic sources.
- Clues to past migrations and contact events (Neolithic farmer expansions, Steppe ancestry pulses, Silk Road interactions, transatlantic movements).
Historical and genetic context
- Modern human populations reflect waves of migration, isolation and admixture: post-glacial recolonization, agricultural diffusion from Anatolia and the Near East, Bronze Age steppe movements, transcontinental trade and recent colonial-era gene flow. K23 frames individual genomes against these patterns using contemporary reference clusters.

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
