关于此计算器
Modern World K28 is a curated K=28 admixture calculator designed to dissect contemporary global ancestry into 29 well-chosen reference components. It analyzes autosomal DNA to estimate the proportional contributions from modern and regionally informative populations — from African hunter-gatherers, Bantu and West African groups to Europe’s British, Iberian, Italian and Balkan clusters; from diverse Asian components including South, East, NorthEast and Southeast Asia, to Central Asian (Iranic, North, South) and Austronesian signals; and to Oceanian and Indigenous American ancestries. Built for a broad audience — genetic genealogists, population geneticists, anthropologists, and curious individuals with diverse backgrounds — this tool translates genome-wide variation into accessible regional affinities.
Users gain quantitative insights into recent and relatively deep ancestry: which continental and regional lineages are present, approximate proportion estimates, and comparative affinities among neighboring populations. Because the reference set is curated for the modern era, it highlights patterns shaped by historical migrations and demographic events such as the Bantu expansion, Eurasian steppe movements, Mediterranean and Balkan admixture, Austronesian dispersal, and Native American roots, while also distinguishing finer European and Asian substructure.
Modern World K28 is valuable because it balances global breadth with regional resolution. It helps validate other ancestry reports, guides further genealogical research, and provides teaching-ready results for understanding how historical population dynamics are reflected in individual genomes. Results are best interpreted alongside historical, archaeological, and genealogical context: proportions are model estimates, not definitive labels, but they offer a clear, quantitative snapshot of how an individual’s DNA relates to contemporary world populations.

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 28 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 28 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
