Dodecad K12b

Dodecad K12b is a modern 12-component admixture calculator designed to estimate the proportional ancestry of individuals from around the world. Using twelve reference components—Gedrosia, Siberian, Northwest African, Southeast Asian, Atlantic Med, North European, South Asian, East African, Southwest Asian, East Asian, Caucasus, and Sub-Saharan—the calculator evaluates genome-wide allele frequencies to produce a concise profile of ancestral affinities. It is intended for genetic genealogy enthusiasts, population geneticists, students of human history, and anyone curious about the broad continental and regional roots of their DNA. This tool translates genetic variation into intuitive percentages that reflect shared ancestry with the named reference groups. Users gain insights into recent and deep ancestry: major continental contributions (for example, Sub-Saharan or East Asian), regional signatures (Caucasus, Atlantic Med), and smaller admixture signals that may reveal past migrations or contacts. The components are interpretable in historical context—Gedrosia highlighting Southwest Asian/Iran plateau affinities, Siberian reflecting northern Eurasian input, Northwest African and Atlantic Med capturing Mediterranean and Maghrebi legacies, and so on—offering a bridge between genetic data and archaeological, linguistic, and historical frameworks. Dodecad K12b is valuable because it provides a balanced, globally oriented lens for ancestry inference: its twelve components cover major Eurasian, African, and Asian genetic structure while remaining simple enough for non-specialists to read. It is not a definitive biography of one’s past but a model-based snapshot: results depend on the reference panel, marker density, and statistical assumptions. For fuller interpretation, combine K12b results with uniparental markers, local population studies, historical records, and other admixture models.
