Admixture Calculator

Dodecad World 9

**Dodecad World 9** gives a clear, modern breakdown of autosomal ancestry using nine global reference components (Amerindian, East Asian, African, Atlantic Baltic, Australasian, Siberian, Caucasus Gedrosia, Southern, South Asian). Ideal for researchers and enthusiasts, it reveals broad migrations and admixture patterns worldwide, offering an intuitive comparative framework while encouraging careful, contextual interpretation.

About This Calculator

**Dodecad World 9 — Modern global admixture calculator** This calculator evaluates genome-wide autosomal variation and breaks an individual's ancestry into proportions of nine modelled components: **Amerindian, East Asian, African, Atlantic Baltic, Australasian, Siberian, Caucasus Gedrosia, Southern,** and **South Asian**. It is a supervised modern-era implementation of the Dodecad-style framework, built to compare personal or population genotypes against globally representative reference clusters. Who it's for - Researchers, genetic genealogy enthusiasts, and educators who want a clear, comparative view of major ancestral influences worldwide. - Individuals seeking context for genetic ancestry beyond single-population labels. What it analyzes and the insights you gain - Estimates relative ancestral proportions derived from nine broad reference clusters. - Reveals mixtures consistent with major prehistoric and historic migrations (e.g., Eurasian steppe fronts, Austronesian expansions, Out-of-Africa dispersals, and Native American founder events). - Highlights affinities to regional reference sets (useful for tracing multi-continental admixture and recent colonial-era gene flow). - Offers a compact, interpretable snapshot that complements deeper haplogroup or local-ancestry analyses. Historical and genetic context The nine components are anchored in populations that reflect deep and recent population structure across the globe. They do not represent discrete ‘‘pure’’ peoples but model signals left by migrations, isolations, and founder events. Interpreting components together provides a narrative of ancestral contributions rather than definitive ethnographic labels. Why this calculator is valuable - Provides an intuitive, reproducible framework for comparing individuals and populations worldwide. - Useful for spotting broad-scale admixture, assessing regional ancestry balance, and generating hypotheses for further study. - Designed for clarity: actionable ou

Reference Populations

The populations used as genetic references in this calculator

9 Reference Populations

Amerindian: Indigenous peoples of the Americas, with roots tracing back to pre-Columbian times.
East Asian: Populations originating from East Asia, including areas such as China, Japan, and Korea.
African: Diverse ethnic groups from the African continent, with a long history spanning thousands of years.
Atlantic Baltic: People from regions around the North and Baltic Seas, primarily including Northern European populations.
Australasian: Indigenous peoples of Australia and surrounding islands, such as Aboriginal Australians and Torres Strait Islanders.
Siberian: Native populations from the Siberian region, known for their adaptation to the extreme climates of Northern Asia.
Caucasus Gedrosia: Groups from the Caucasus region and parts of Iran and Pakistan, historically known for their varied cultural and linguistic mosaic.
Southern: Populations from Southern Europe, characterized by a Mediterranean influence in their culture and history.
South Asian: Diverse populations from the South Asian subcontinent including countries like India, Pakistan, and Bangladesh.

Continents:

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

How It Works

Your DNA is compared to 9 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
