Global Ancestry K25 with Jewish Populations
Global Ancestry K25 — 25-component, world-scale admixture analysis
A modern admixture calculator that estimates ancestry proportions using 25 modeled components anchored to 105 global reference populations. Ideal for anyone worldwide, it reveals regional affinities (Africa, Europe, Middle East, South & Central Asia, East Asia, Siberia, Oceania), highlights multi-way admixture, and helps connect genetic signals to migration and population history. Model-aware and interpretation-friendly.

Global Ancestry K25 — Modern, world-scale admixture calculator
Global Ancestry K25 analyzes an individual's genome and estimates proportional ancestry across 25 modeled components informed by 105 carefully chosen reference populations from Africa, Europe, the Middle East, South and Central Asia, East Asia, Siberia and Oceania. The calculator is designed for anyone worldwide — hobbyists, genealogists, population geneticists, and people curious about their deep and recent ancestry.
What this calculator analyzes:
- Genome-wide allele frequency patterns compared to 105 reference groups (e.g., Yoruba, Druze, Han_NChina, Kalash, Sardinian, Papuan).
- Admixture proportions mapped to 25 interpretable clusters that summarize shared genetic drift and affinity.
Insights you can gain:
- Quantified ancestry proportions (e.g., percent West Eurasian, South Asian, East Asian, Sub-Saharan African, Oceanian, Siberian).
- Regional affinity signals that suggest likely geographic sources of ancestry and mixtures across historical periods.
- Evidence of multi-way admixture, recent immigrant ancestry vs. deep regional heritage, and genetic components consistent with known migration routes.
Historical and genetic context:
K25 is a modern clustering model that compresses genetic variation into 25 components while leveraging a broad set of real reference populations to anchor interpretations. This approach balances resolution and robustness: it is fine-grained enough to distinguish many continental and subcontinental signals, yet conservative enough to avoid overfitting to small sample idiosyncrasies.
Why this calculator is valuable:
- Broad coverage: 105 reference populations provide global context for diverse users.
- Practical: clear, quantitative proportions you can compare across relatives or populations.
- Educational: connects genomic patterns to migration, admixture, and historical population structure.
Limitations and best practices:
- Results are model-dependent: int

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 25 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 25 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
