East Sea K12
East Sea K12 — Modern 12-way admixture
A compact, global-ready calculator that breaks your autosomal DNA into 12 modern reference components (Dai, Han, Korean, Japanese, Mongolian-Tungusic, Yakut, Tibetan, Cambodian, Indian, Amerindian, European, African). Perfect for ancestry enthusiasts and researchers who want clear regional resolution across East, Southeast, Central and global admixture, with contextual historical notes and cautions.

East Sea K12 — Modern 12-way Admixture Calculator
What this calculator analyzes
East Sea K12 decomposes an individual's autosomal DNA into proportions derived from 12 modern reference populations: Dai, Han-Chinese, Korean, Japanese, Mongolian-Tungusic, Yakuts, Tibetan, Cambodian, Indian, Amerindian, European, and African. Using allele-frequency comparisons and clustering across a global dataset, it estimates the fraction of genetic ancestry attributable to each reference group.
Who it's designed for
- Global users curious about their East Asian and adjacent-region ancestry
- Adoptees, genealogy enthusiasts, and family researchers seeking regional signals
- Students and researchers who want a compact, interpretable 12-component view
Insights you can gain
- Relative contributions from East, Southeast, Central, South Asian, and distant continental sources
- Clear distinction between East Asian sub-regions (e.g., Han vs. Korean vs. Japanese) and northern steppe-related signals (Mongolian-Tungusic, Yakut)
- Detection of low-level continental admixture (European, African, Amerindian)
- Hypotheses about recent versus deep ancestry when combined with personal history
Historical and genetic context
The panel reflects modern population structure shaped by migrations and contact: southward Austroasiatic and Tai movements (Dai, Cambodian), northeast Asian expansions (Korean, Japanese, Mongolic/Tungusic), highland Tibeto-Burman lineages (Tibetan), Central Asian/North Eurasian influences (Yakut, Mongolian-Tungusic), and long-range gene flow via trade routes and colonial era contacts that introduce European, African, and Amerindian signals.
Why this calculator is valuable
- Offers a focused, interpretable snapshot (K=12) that balances regional resolution and global context
- Helps users place their DNA within a modern East Asian–centric framework while still accounting for wider admixture
- Useful as a starting point for deeper research, g

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 12 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 12 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
