Modern World Kakaji K20
Modern World Kakaji K20 offers a 20-population admixture breakdown that maps your DNA to a curated panel spanning Africa, Europe, the Middle East, South & East Asia, Siberia, and the Americas. Ideal for genetic genealogy, research, and education, it provides interpretable ancestry proportions and insights into recent gene flow and regional affinities — with clear caveats about model dependence.

Modern World Kakaji K20 — What this calculator analyzes
This calculator decomposes an individual genotype into contributions from 20 modern reference populations, producing a fine-grained admixture profile for the contemporary world. It compares your DNA to a curated panel that spans Sub-Saharan Africa, North Africa and the Middle East, Europe, South Asia, East and Northeast Asia, Siberia, and Indigenous America to estimate relative ancestry proportions.
Who it’s designed for
- Genetic genealogy enthusiasts seeking regional affinities
- Researchers and students exploring population structure and recent admixture
- Educators demonstrating real-world examples of human genetic diversity
Reference panel highlights
Includes representative groups such as Lahu, Naxi, Dai, Japanese, Yakut (East & Northeast Asia); Tamil, Telegu, Makrani, Kalash (South & Central Asia); Finn, Sardinian (Europe); Druze, Bedouin, Mozabite (Middle East/North Africa); Gambian, Esan, Mbuti and Biaka Pygmies (diverse African ancestries); and Karitiana, Pima (Indigenous America).
Insights you can gain
- Quantitative ancestry proportions against 20 modern populations
- Detection of mixed regional signals (for example, South Asian + West Eurasian or East Asian + Siberian)
- Clues about recent gene flow, historical migrations, and population contact zones
Historical and genetic context
The panel reflects both ancient deep splits (e.g., Sub-Saharan vs. non‑African) and recent regional structure shaped by migrations, trade, and isolation (e.g., island Sardinian drift, Siberian Yakut ancestry, Andean/Amazonian Americas). The inclusion of pygmy and Saharan/North African references helps resolve African substructure often missed in coarse models.
Why this calculator is valuable
- Provides a balanced, interpretable K=20 breakdown that is more granular than broad continental models
- Useful for mapping likely regional affinities and recent admixture events
- A practical teach

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 20 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 20 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
