Admixture Calculator

Dodecad V3

**Dodecad V3 — Global admixture in 13 components** A compact, modern admixture calculator that deconvolves autosomal DNA into 13 global reference components (European, Asian, African, Amerindian and subregions). Ideal for ancestry explorers, genealogists, and researchers seeking a clear, comparable snapshot of regional affinities and historical admixture signals. Use with complementary analyses for best insights.

About This Calculator

**Dodecad V3 — Global Admixture Calculator (Modern era)** Dodecad V3 analyzes genome-wide autosomal variation to estimate ancestry proportions against a compact, interpretable set of 13 reference components that span the modern world. Using model-based ancestry deconvolution, it places an individual's DNA on a global palette of genetic ancestry: East_European, West_European, Mediterranean, West_Asian, South_Asian, Northeast_Asian, Southeast_Asian, Southwest_Asian, Neo_African, East_African, Northwest_African, Palaeo_African, and Amerindian. Who it’s for: - Individuals curious about deep and recent ancestry - Genealogists and hobbyists seeking regional affinity signals - Population geneticists and students needing a compact reference framework - Cultural and historical researchers exploring migration patterns What you gain: - Quantitative ancestry proportions expressed across 13 well-differentiated components - A clear, comparable snapshot of regional affinities useful for personal reports or research summaries - Contextual clues about historical admixture events (e.g., Eurasian steppe influence, African diaspora, Austronesian expansion) when combined with time-aware interpretation Why it matters: Dodecad V3 balances breadth and interpretability. Thirteen components are few enough to remain intuitive yet broad enough to capture major continental and subcontinental signals. This makes the calculator especially useful when you want a concise, global view rather than an overly fragmented breakdown. Important notes: - Results are model-based estimates, not deterministic identities; component labels reflect reference clusters, not exclusive populations. - Resolution depends on the reference set; fine-scale local ancestry may require regional panels. - Best used alongside PCA, haplotype analyses, or historical records for richer interpretation. Dodecad V3 is designed to be a clear, scientifically grounded tool that helps users translate genetic variation into meaning

Reference Populations

The populations used as genetic references in this calculator

0 Reference Populations

European

East_European: Populations primarily from Eastern Europe, known for Slavic languages and cultures.
West_European: Populations from Western Europe, encompassing Germanic and Romance language-speaking regions.
Mediterranean: Populations around the Mediterranean Basin, including Southern European, Middle Eastern, and North African influences.

Asian

West_Asian: Populations from regions such as the Caucasus, Turkey, and parts of the Middle East.
South_Asian: Populations from the Indian subcontinent, known for diverse languages and cultures.
Northeast_Asian: Populations from areas like China, Korea, and Japan, characterized by East Asian cultures.
Southeast_Asian: Populations from countries in Southeast Asia, with diverse ethnic groups and languages.
Southwest_Asian: Populations from the Arabian Peninsula and Middle Eastern regions, rich in ancient history.

African

Neo_African: Populations from more recently evolved African lineages, including sub-Saharan regions.
East_African: Populations from the eastern part of the African continent, known for a mixture of cultures and languages.
Northwest_African: Populations from the Maghreb region, influenced by Berber and Arab cultures.
Palaeo_African: Populations from ancient African lineages, possibly representing some of the oldest human ancestries.

Amerindian

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

How It Works

Your DNA is compared to 0 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
