About This Calculator

**Dodecad Euro 7 — Modern 7-way admixture model** This calculator estimates the proportional ancestry of an individual across seven broad reference components: **Caucasus, Northwestern, Northeastern, Southeastern, African, Far_Asian,** and **Southwestern**. Built from modern population allele-frequency patterns, the model reduces complex genomic variation into an interpretable seven-part profile that highlights major continental and regional contributions. Who it's for - Genetic genealogy enthusiasts and informed users seeking a clear, compact breakdown of ancestral contributions. - Population geneticists and students who want a rapid comparative tool to explore broad patterns across the globe. - Researchers comparing modern samples to historical trends or ancient genomes. What it analyzes and the insights you can gain - Estimates relative ancestry proportions by comparing your genotype to reference panels representing the seven components. - Reveals broad biogeographic affinities (e.g., stronger Caucasus or Far_Asian signals) and minor admixture fractions such as African or Southwestern input. - Helps interpret clines and regional structure within Eurasia: Northwestern/Northeastern/Southeastern components capture internal European variation while Caucasus and Southwestern reflect Near Eastern and Anatolian influences. - Useful for spotting unexpected gene flow, guiding deeper regional testing, or contextualizing family history. Context and limitations - The labels are descriptive proxies for allele-frequency clusters, not precise ethnic or national labels. Components reflect recent and ancient mixtures; results are relative, not absolute. - This is a modern-era model optimized for global comparisons with emphasis on Eurasian substructure. It is not a clinical test. Why this calculator is valuable - Provides a balanced, easy-to-interpret seven-component summary that preserves meaningful resolution without overwhelming detail. - Ideal as a first-pass tool to

Reference Populations

The populations used as genetic references in this calculator

7 Reference Populations

Caucasus: Encompasses diverse ethnic groups mainly from the mountainous regions between Europe and Asia such as Armenians and Georgians.
Northwestern: Refers to populations from Northwestern Europe, including areas like the British Isles and Scandinavia.
Northeastern: This typically includes populations from Northeastern Europe, encompassing countries like Russia and the Baltic states.
Southeastern: Populations primarily from Southeastern Europe, such as the Balkans.
African: Encompasses the diverse ethnic populations across the African continent.
Far_Asian: Populations from East Asia, including countries such as China, Japan, and Korea.
Southwestern: Usually refers to populations from Southwestern Europe, like the Iberian Peninsula.

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

How It Works

Your DNA is compared to 7 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
