Description
Dodecad Globe 13 analyzes genome-wide autosomal genotype data to estimate the proportional ancestry an individual shares with 15 geographically and historically informed reference populations: 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. Built for a global audience â researchers, genetic genealogists, educators, and curious users â the calculator converts SNP data into a concise admixture profile that highlights both dominant ancestry blocks and subtle minority contributions.
Using a model-based admixture framework and a modern reference panel, Dodecad Globe 13 balances resolution and stability: broad continental clusters describe major affinities while regionally specific components reveal finer structure across Eurasia, Africa, Oceania, and the Americas. The output gives percentage estimates for each component, enabling comparisons across individuals or populations, detection of unexpected signals (for example, minor Australasian or Arctic ancestry), and exploration of historical processes such as ancient migrations, back-migrations, founder events, and recent gene flow.
This calculator is valuable because it translates complex genetic variation into interpretable results that complement uniparental markers and documentary genealogy. It is suitable for hypothesis generation, educational demonstrations of human diversity, and cross-population comparisons in population genetics. Important caveats: results are probabilistic and depend on the chosen reference samples and model assumptions; they do not provide precise dates or identify specific ancestors. For robust inference, pair Dodecad Globe 13 results with additional analyses (regional datasets, haplogroups, formal tests) and consider historical, archaeological, and linguistic context.

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.
What is Admixture Analysis?
Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.
This calculator uses 13 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
Key Points
- Your DNA is compared to 13 reference populations
- Modern populations are used as references
- Results show your genetic similarity to these populations
Understanding Your Results
Your results will show percentages of genetic similarity to these reference populations. Remember:
- Results reflect genetic similarity, not direct ancestry
- Modern populations are used as references
- Percentages indicate relative genetic contribution from each population
- Results are estimates based on available reference data
