Dodecad K12b — Modern 12-way Admixture Calculator
Dodecad K12b is a modern, global admixture calculator that decomposes an individual's genome into twelve ancestral components derived from broad reference populations. It analyzes allele frequency patterns across the genome to estimate proportional ancestry from: Gedrosia, Siberian, Northwest African, Southeast Asian, Atlantic Mediterranean, North European, South Asian, East African, Southwest Asian, East Asian, Caucasus, and Sub-Saharan groups.
Who it's for
- Genetic enthusiasts, genealogists, and curious individuals seeking a clear, comparative view of their deep ancestry
- Researchers and students who need a convenient, standardized 12-component breakdown for population comparisons
What you gain
- A breakdown of ancestry proportions that highlights major continental and regional contributions
- Contextual interpretation: which components typically reflect West Eurasian, African, South Asian, and East Asian heritage
- A starting point for historical inference—migration signals, admixture events, and regional affinities—when combined with archaeological and linguistic evidence
Genetic and historical context
K12b is an allele-frequency based model optimized for modern populations: it captures long-term regional differentiation rather than single recent genealogical events. Components like Gedrosia and Caucasus reflect shared West Asian ancestries, while Atlantic Med and North European resolve diverse European contributions. Asian and African diversity are represented through East Asian, Southeast Asian, Siberian, East African, and Sub-Saharan components.
Why use Dodecad K12b
- Balanced resolution: twelve components provide interpretable regional signals without overfitting
- Global scope: designed for worldwide application, useful for multi-ethnic samples
- Comparative utility: easy to compare individuals, populations, and published datasets

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
