Global Ancestry K31
Global Ancestry K31 — a modern K=31 admixture calculator using 31 regional reference populations across Africa, Europe, Asia, Oceania and the Americas. It provides fine-grained autosomal ancestry proportions, reveals regional admixture signals and historical influences, and is designed for genealogists, researchers, and ancestry enthusiasts. Results are probabilistic and best interpreted with historical and genealogical context.

关于此计算器
Global Ancestry K31 — a modern-era, 31-cluster admixture model tuned for worldwide comparisons. This calculator compares your genotype to a curated panel of 31 regional reference populations spanning Africa, Europe, Asia, Oceania, and the Americas to estimate ancestral proportions and reveal fine-scale continental and subcontinental signals.
What this analyzes
- Autosomal ancestry proportions across 32 inferred clusters derived from 31 named reference populations (e.g., Central African, West African, East Asian, South Asian, West Asian, Balkan, Scandinavian, Native American, Papuan/Melanesian, Amazonian, etc.).
- Patterns of recent admixture and deeper population structure that reflect migrations, isolation, and historical contact.
Who it's designed for
- Genealogists and ancestry enthusiasts seeking finer regional resolution than broad continental tests.
- Population geneticists and educators who want an accessible visualization of modern global diversity.
- Anyone curious about mixed heritage, recent migrations, or regional affinities.
Insights you can gain
- Percentage estimates of ancestry tied to specific regional clusters.
- Signals of historical events (e.g., Bantu expansion, Eurasian steppe influence, Austronesian dispersals, European colonial admixture, Native American population structure).
- How your genetic profile compares to contemporary reference groups and which regions contributed most to your autosomal DNA.
Context & limitations
- The model reflects modern reference samples; clusters are statistical constructs, not strict ethnic labels.
- Jewish-specific clusters were intentionally excluded; consequently Levantine or Mediterranean ancestry may map to neighboring West Asian, Middle Eastern, or Southern European components.
- Results are probabilistic and influenced by reference coverage and sample size. Use alongside genealogical records and uniparental tests for a fuller picture.

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 31 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 31 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
