Admixture Calculator

Dodecad Globe 10

**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

About This Calculator

**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

Reference Populations

The populations used as genetic references in this calculator

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.

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

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 10 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 10 reference populations
Modern populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Modern populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
