Dodecad Weac 2

Dodecad Weac 2 — Global seven‑way admixture calculator

What this calculator analyzes

Dodecad Weac 2 performs model‑based autosomal ancestry deconvolution to estimate the proportion of a person’s genome that best matches seven broad reference components. Using genome‑wide SNP data, it returns percent ancestry from the following reference populations:

• Palaeoafrican
• Atlantic_Baltic
• Northeast_Asian
• Near_East
• Sub_Saharan
• South_Asian
• Southeast_Asian

Who it's designed for

This tool is built for a global audience: genealogists, population geneticists, curious consumers of ancestry reports, and anyone seeking a concise, research‑grade snapshot of deep and recent admixture patterns across the world. It is tuned for modern-era samples and is most informative when applied to high‑quality autosomal SNP data.

Insights you can gain

• Quantified ancestry proportions across seven continental/regional clusters
• A clear view of major admixture signals (e.g., European vs. East Asian vs. African components)
• Context for migration, contact zones, and multiethnic ancestry in individuals or small cohorts

Historical and genetic context

These seven components capture major branches of human population structure shaped by ancient splits and more recent migrations: Out‑of‑Africa dispersals, Eurasian expansions, South and Southeast Asian differentiation, and later regional admixture. The labels are broad and reflect reference clusters rather than precise ethnicities.

Why this calculator is valuable

Dodecad Weac 2 provides an accessible, scientifically grounded summary of ancestry that complements genealogical records and deeper population studies. It is fast, interpretable, and useful for comparative analyses across samples. Users should interpret results as probabilistic estimates—sensitive to reference composition and SNP overlap—rather than exact cultural or national labels. For robust interpretation, combine thes
