Dodecad Weac

Dodecad Weac is a modern genetic admixture calculator that estimates an individual's autosomal ancestry as proportions across four broad, globally informed reference clusters: Atlantic-Baltic, Near‑East, Far‑East, and Africa. Built for a worldwide audience, it provides an accessible yet scientifically grounded snapshot of the major ancestral components that shaped a contemporary genome. The calculator compares a user's genotype to curated reference allele-frequency panels and decomposes the genome into relative percentages for each reference population. This produces clear, quantitative results that help users — from genealogists and educators to population geneticists and curious consumers — interpret continental and large-scale regional ancestry. Examples of the insights users can gain include detection of subtle African input in Eurasian histories, Near‑Eastern influence across Mediterranean and Central Asian populations, Far‑East signals extending into Siberia and Northeast Eurasia, and the Atlantic‑Baltic signature common to northwest Europe. The four reference axes were selected to capture dominant dimensions of global genetic structure: Atlantic‑Baltic (northwest Eurasia), Near‑East (West Asia/Levantine), Far‑East (East and Southeast Asia), and Africa (sub‑Saharan diversity). Placing a profile within this framework helps translate abstract percentages into historical processes such as migrations, admixture pulses, and long-term regional continuity. Dodecad Weac is valuable because it blends rigorous allele-frequency methods with clarity and usability. It is optimized for modern-era genotype data and updated reference sets, making it a dependable first-pass tool for research triage, teaching, and personal exploration. Users should interpret results alongside geographic, archaeological, and genealogical context: the calculator highlights broad patterns, not fine-scale local ancestry. For deeper resolution, haplotype-based or region-specific analyses are reco
