GedrosiaDNA Eurasia K14
GedrosiaDNA Eurasia K14 is a 14-component admixture calculator that breaks your DNA into global and Eurasian ancestry proportions using well-chosen reference proxies (Kalash, Steppe, SW Asian, NE European, SE Asian, Papuan, Sub-Saharan, and more). Ideal for genealogists and researchers, it highlights deep and recent admixture signals, reveals regional signatures, and helps interpret migration and contact histories. Results are model-based proxies, not definitive ancestors.

关于此计算器
GedrosiaDNA Eurasia K14 is a 14-component admixture calculator that decomposes a tested genome into ancestry proportions using geographically and genetically informative reference groups. It is designed to give a broad, interpretable portrait of global and Eurasian ancestry by combining deep regional signatures (e.g., Steppe, SW Asian, NE European) with more isolated or distinctive proxies (e.g., Kalash, Papuan).
What this calculator analyzes
- Proportional ancestry across 14 reference populations: Kalash, SE Asian, Siberian, S Indian, Papuan, SW European, N Amerindian, Steppe, Pygmy, NE Asian, Sub-Saharan, SW Asian, NE European, S Amerindian.
- Relative contributions that reflect both ancient population structure (e.g., Steppe vs. SW Asian inputs) and recent regional admixture (e.g., SE Asian vs. NE Asian components).
Who it's designed for
- Individuals seeking detailed, cross-continental ancestry breakdowns.
- Amateur and professional genetic genealogists, population geneticists, and historians exploring migration patterns and admixture.
- Anyone wanting to place their DNA within broad Eurasian and global contexts.
Insights you can gain
- Detection of continental and regional ancestry proportions (e.g., Steppe-derived, Southwest Asian, Siberian, or Oceanian signals).
- Identification of uncommon or focal signatures (e.g., Kalash-like ancestry) that can indicate specialized regional histories.
- Comparative perspective on how your profile aligns with populations across Eurasia, the Americas, Africa, and Oceania.
Historical and genetic context
This model uses modern reference proxies to approximate historical ancestries. Components like "Steppe" capture gene flow associated with Bronze Age movements, while SW Asian and NE European traces reflect long-term demographic structure and later migrations. Isolated proxies (Kalash, Pygmy, Papuan) help flag regionally distinctive ancestry.
Why this calculator is valuable
- Broad geographic coverage lets you

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 14 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 14 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
