Dodecad Globe 4
Dodecad Globe 4 — Global modern admixture calculator
A scientifically grounded autosomal admixture tool that estimates ancestry proportions across 21 global reference populations. Designed for researchers, genealogists, and curious individuals, it reveals continental and subcontinental components (European, African, Asian, Amerindian) to illuminate migration, contact, and recent admixture—presented clearly and quantitatively.

Dodecad Globe 4 — Modern Global Admixture Explorer
Dodecad Globe 4 is an autosomal admixture calculator optimized for modern, world-wide genetic datasets. It estimates proportional ancestry from 21 reference populations, spanning broad continental groups and fine-grained subregions (European, Asian, African, and Indigenous American components). The calculator analyzes genome-wide SNP data to produce a compositional portrait of an individual's recent and deep ancestry.
Who it's for:
- Researchers and population geneticists seeking a comparative global panel
- Genealogists and curious individuals exploring multi-continental roots
- Anthropologists and historians interpreting migration signatures
What you learn:
- Quantitative ancestry proportions across 21 reference populations (e.g., Northwest European, South Asian, West African, Andean)
- Biogeographic affinities and likely regional signals
- Detection of minor components that reflect historical contact (trade routes, colonization, or recent admixture)
Historical and genetic context: Human populations carry layered signatures of ancient migrations (Out of Africa, Eurasian expansions), regional founder events, and recent movements (colonization, slave trade, intercontinental migration). Dodecad Globe 4 frames your genome against this context, highlighting how continental and subcontinental ancestries combine in modern individuals and populations.
Why it matters:
- Broad, globally balanced reference set captures diversity across continents and Indigenous American subregions
- Useful for hypothesis generation about population history and recent admixture
- Presents results in an interpretable, quantitative format suitable for comparison across samples
Important caveats:
- Results are probabilistic and depend on the chosen reference panel; small component estimates are sensitive to reference composition
- Interpret outputs alongside historical, genealogical, and archaeological evidence for best inference

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 4 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 4 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
