Dodecad Weac — Modern four-way admixture calculator

Dodecad Weac is a compact, intuitive autosomal admixture calculator that models an individual's ancestry as proportions of four broad reference populations: Atlantic–Baltic, Near‑East, Far‑East, and Africa. Designed for modern samples from anywhere in the world, it summarizes genome-wide SNP variation into a clear, interpretable four‑component profile.

What this calculator analyzes

• Genome‑wide autosomal markers to estimate the proportion of ancestry traceable to each of the four reference axes.
• Population‑level allele frequency contrasts to resolve broad continental and subcontinental signals.

Who it's designed for

• Enthusiastic genealogists and family historians seeking big‑picture ancestry breakdowns.
• Researchers and students who want a simple, reproducible four‑way model for exploratory analyses.
• Curious individuals worldwide who want a concise summary of major continental contributions to their genome.

Insights you can gain

• Relative contributions from Atlantic–Baltic, Near‑Eastern, Far‑Eastern, and African source clusters.
• Broad historical signals such as Eurasian clines, signals of transcontinental admixture, and major migration legacies (e.g., movements across Eurasia, Near‑Eastern expansions, and African gene flow).
• A starting point for deeper analysis: results can guide targeted follow‑up with higher‑resolution regional panels or haplotype‑based methods.

Context and limitations

• The four‑component model is deliberately simple: it emphasizes clarity over fine regional detail. It captures major ancestry streams shaped by events like Out‑of‑Africa dispersals, Holocene farmer and pastoralist movements, and later regional contacts.
• Interpret results as approximations tied to the chosen reference sets; they are best combined with historical, archaeological, and regional genetic evidence.

Why this calculator is valuable

• Fast, accessible, and easy to interpret—idea
