Dodecad World 9

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
