Dodecad Globe 10 — Modern global admixture at a glance
A compact admixture calculator that quantifies an individual's genetic ancestry across nine global reference components (Amerindian, West_Asian, Australasian, Palaeo_African, Neo_African, Siberian, Southern East_Asian, Atlantic_Baltic, South_Asian). Ideal for researchers, genealogists, and curious users worldwide, it provides clear proportional breakdowns and insights into major and subtle ancestral signals while noting limits of resolu

Dodecad Globe 10 — Modern-era global admixture calculator
This calculator estimates the proportional genetic ancestry of a modern individual against nine global reference populations. Using allele-frequency–based admixture modelling, Dodecad Globe 10 places a user's genotype into a global context and returns interpretable component weights that reflect deep and recent population history.
Who it's for
- Researchers, genetic genealogists, and curious individuals seeking a clear, comparative view of worldwide ancestry.
- People with multicultural backgrounds who want to parse continental and regional signals.
What it analyzes
- Relative contributions from nine reference components: Amerindian, West_Asian, Australasian, Palaeo_African, Neo_African, Siberian, Southern East_Asian, Atlantic_Baltic, and South_Asian.
- The output highlights dominant ancestry fractions and subtle secondary signals that can indicate past migrations or admixture events.
Insights you can gain
- A concise breakdown of global ancestry proportions for modern individuals from any region.
- Detection of major continental roots (e.g., African, Eurasian, Native American) and finer regional affinities (e.g., Atlantic/Baltic versus West Asian or South Asian inputs).
- Clues about historical processes such as Out-of-Africa-related diversity, Holocene Eurasian expansions, transoceanic dispersals, and regional admixture patterns.
Why it’s valuable
- Offers a reproducible, comparative framework for interpreting individual genomes against a compact set of meaningful reference clusters.
- Useful as a starting point for deeper population-genetic or genealogical investigation; results are quantitative, easy to compare across samples, and informative for global-scale interpretation.
Important caveats
- Component labels are heuristic: they summarize genetic similarity to reference groups rather than defining cultural or ethnic identity. Resolution depends on reference selection and sample density
参考人口
计算器中用作遗传参考的种群
10 Reference Populations
Amerindian: Indigenous peoples of the Americas, including First Nations, Inuit, and Métis in Canada, Native Americans in the United States, and Indigenous peoples of Latin America.
West_Asian: Populations originating from the Western Asia region, including countries such as Iran, Turkey, Iraq, and the Caucasus region.
Australasian: Indigenous peoples of Australia, including Aboriginal Australians and Torres Strait Islanders, and the peoples of Melanesia, Micronesia, and Polynesia in the Pacific Islands.
Palaeo_African: Ancient populations in Africa with distinct genetic signatures predating the widespread influence of Bantu migrations.
Neo_African: Includes populations from recent African lineages primarily influenced by the Bantu expansion, incorporating Sub-Saharan African groups.
Siberian: Peoples inhabiting Siberia, such as the Evenki, Nenets, and other indigenous Siberian groups.
Southern East_Asian: Populations from the southern regions of East Asia, including parts of China, Vietnam, Thailand, and neighboring areas.
Atlantic_Baltic: Populations from Northern Europe along the Atlantic Ocean and the Baltic Sea, including Scandinavian and Baltic peoples.
South_Asian: Groups from the Indian subcontinent, including India, Pakistan, Bangladesh, Nepal, Bhutan, and Sri Lanka.

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 10 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 10 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
