Dodecad Globe 13
Dodecad Globe 13 is a modern, global admixture calculator that estimates your ancestry as proportions from 15 reference populations (African, Eurasian, Amerindian, Australasian, Arctic and regional subgroups). Ideal for genealogists, students, and researchers, it reveals regional affinities and historical admixture signals while providing a nuanced, comparative view of your genetic heritage.

Dodecad Globe 13 — Modern global admixture calculator
Dodecad Globe 13 estimates an individual's genetic ancestry as proportions from 15 globally distributed reference populations. It compares your genotype against allele-frequency clusters representing major continental and regional groups to give a readable, comparative profile of ancestral components in a modern, world-wide context.
What this calculator analyzes
- Proportional ancestry contributions from: Siberian Amerindian, African, West African, Palaeo African, East African, Asian, East Asian, South Asian, Southwest Asian, West Asian, European, Mediterranean, North European, Australasian, and Arctic.
- Relative affinities created by shared genetic drift and allele-frequency patterns across populations.
Who it's designed for
- Genealogy enthusiasts and curious individuals exploring personal ancestry.
- Students and educators illustrating patterns of human diversity.
- Population geneticists and researchers seeking a compact comparative view.
Insights you can gain
- Estimated percentage ancestry from each reference cluster.
- Signals of historical migrations and admixture (e.g., Eurasian steppe, African dispersals, Australasian or Arctic affinities).
- Fine distinctions among nearby Eurasian components (North European vs Mediterranean vs West Asian) and among African regional clusters.
Historical and genetic context Human genetic variation reflects repeated migrations, isolations, and admixture events — out-of-Africa dispersals, the peopling of the Americas, Holocene expansions across Eurasia, and maritime movements into Australasia and the Arctic. Dodecad Globe 13 places your genome within that tapestry using modern comparative samples.
Why this calculator is valuable
- Global scope with 15 informative reference clusters offers nuanced results beyond broad continental labels.
- Useful as an interpretive tool alongside documentary genealogy, archaeology, and other genetic evidence.
参考人口
计算器中用作遗传参考的种群
13 Reference Populations
Siberian Amerindian
- Description: Populations native to Siberia and American indigenous peoples sharing genetic connections. Influences from ancient migrations across the Bering Strait.
African
West African
- Description: Populations from West Africa, known for rich genetic diversity and history predating colonial times.
Palaeo African
- Description: Ancient African populations, providing insight into early human evolution and migration within the continent.
East African
- Description: Diverse ethnic groups from eastern Africa, encompassing Swahili coast cultures and the Great Lakes region.
Asian
East Asian
- Description: Populations from China, Korea, Japan, and Mongolia, with shared cultural and historical backgrounds.
South Asian
- Description: Encompasses Indian, Pakistani, Sri Lankan, and Bangladeshi ethnicities with a long history of trade and cultural exchange.
Southwest Asian
- Description: Refers to Middle Eastern populations, with significant historical civilizations such as Mesopotamia and the Levant.
West Asian
- Description: Encompasses populations from regions like Iran and the Caucasus, historically significant for ancient empires.
European
Mediterranean
- Description: Coastal populations of Southern Europe, North Africa, and the Near East, diverse due to extensive maritime trade.
North European
- Description: Includes populations from Northern Europe like Scandinavia, characterized by fair skin and diverse linguistic roots.
Australasian
- Description: Encompasses Aboriginal Australians and Pacific Islanders, who have unique genetic markers and deep-rooted indigenous traditions.
Arctic
- Description: Populations from the Arctic regions, such as Inuit and Saami, adapted to cold climates with specialized cultural practices.

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 13 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 13 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
