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
