Global Ancestry K27 with Jewish Populations
Global Ancestry K27 — Modern, high-resolution admixture analysis
Compare your autosomal DNA to 21 curated regional references to receive clear percentages of continental and subcontinental ancestry. Ideal for genealogy enthusiasts, adoptees, and researchers, K27 highlights modern-era migration signals (e.g., Mediterranean, Eurasian, African, Oceanian) while noting statistical uncertainty and reference limits.

Global Ancestry K27 — Modern, continental-to-subcontinental admixture analysis
Global Ancestry K27 evaluates your autosomal DNA against a curated set of 21 regional reference populations to produce a clear, quantitative portrait of genetic ancestry. Designed for people with genotype data from consumer labs (e.g., 23andMe, AncestryDNA, MyHeritage) as well as genealogists, adoptees, educators, and population geneticists, this calculator emphasizes modern-era, high-resolution continental and subcontinental signals.
What it analyzes:
- Genome-wide autosomal markers compared to reference groups including East Asian, West African, North African, Anatolia/Caucasus/Iranian Plateau, Sardinian, Ashkenazi Jewish, Scandinavia, Oceania, the Americas, and more.
- Relative ancestry proportions that reflect both recent admixture and deeper regional affinities.
Insights you can gain:
- Estimated percentage contributions from major world regions and specific subregions (e.g., North Italy vs. Iberian; Central Indian vs. Southern Indian).
- Signals that illuminate recent family history (multi-generational mixing) and broader migration patterns (e.g., Eurasian steppe, Mediterranean exchanges, trans-Atlantic movement).
- Identification of distinctive components such as Sardinian-like isolation, Ashkenazi Jewish genetic clusters, or Oceania-specific ancestry.
Historical and genetic context: K27 is framed for the modern era: it highlights population structure shaped by documented historical migrations, trade routes, and demographic events rather than deep Paleolithic splits alone. Reference populations reflect both geographically and culturally informative groups (e.g., Anatolia/Caucasus/Iranian Plateau to capture Near Eastern inputs; North British Isles and Scandinavia for northern European substructure).
Why this calculator is valuable:
- Offers balanced, interpretable subcontinental resolution useful for personal genealogy and research.
- Presents results with clear caveats abo

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
