Global Ancestry K28 — Modern autosomal admixture at continental and regional resolution
This calculator analyzes your autosomal DNA and estimates the proportional ancestry you share with a curated set of modern reference populations. Using a high-resolution K28-style model tuned to 23 broad and regional groups, the tool places your genome on a continuum from continental-scale components (African, East Asian, European, Amerindian) down to regional clusters (Anatolian, Levantine, West Med, Horn of Africa, Siberian, Finnic, South Asian, etc.).
Who it’s for
- Genealogy enthusiasts and adoptees seeking detailed family origins
- Students and researchers comparing population structure in modern cohorts
- Anyone curious about how recent and ancient migrations shape personal ancestry
What insights you gain
- A proportional breakdown of ancestry across 23 modern reference groups
- Highlights of likely regional contributions (e.g., Anatolian farmer-related, Steppe-associated, West African, East African/ Horn signals)
- Context for unexpected components (historic trade routes, colonial-era admixture, long-distance migrations)
Historical and genetic context Human populations are the product of repeated migrations, isolates and mixtures: Out-of-Africa dispersals, Neolithic farming spread from Anatolia, Bronze Age steppe movements, Silk Road contacts, and more recent colonial and slave-trade-era exchanges. This calculator situates your DNA within that continuum using contemporary reference samples representing those geographic and historical legacies.
Why this calculator is valuable
- Balances broad continental categories with focused regional clusters for nuanced interpretation
- Designed for clarity: proportions are presented as interpretable components rather than deterministic labels
- Useful as a starting point for deeper research, genealogical triangulation, or curiosity-driven exploration
Notes: this is an ancestry inference tool, not a medical tes

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 27 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 27 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
