Dodecad World 9

Dodecad World 9 is a modern-era genetic admixture calculator that decomposes a DNA sample into nine broad ancestral components: Amerindian, East Asian, African, Atlantic Baltic, Australasian, Siberian, Caucasus-Gedrosia, Southern, and South Asian. It is built for a global audience — hobbyist and professional genetic genealogists, population geneticists, students, and anyone curious about the geographic roots of modern genomes — who want an interpretable, comparative picture of ancestral mixtures. The calculator analyzes allele-frequency patterns across informative markers and projects samples onto clusters derived from worldwide reference populations. The named components represent statistical genetic clusters tied to major historical and geographic affinities rather than strict ethnic categories; for example, Caucasus-Gedrosia captures West Asian/Near Eastern signals, Atlantic Baltic indicates northwestern European affinities, and Siberian and Australasian identify deeper Northeastern Eurasian and Oceanian links. Users gain several practical insights: percentage breakdowns of continental and subcontinental ancestry, identification of minority or unexpected ancestries, and comparative placement against global baselines. Results can highlight large-scale processes — migrations, admixture clines, and population contacts — visible in modern genomes, and can help formulate questions for deeper study or cross-check family histories. Dodecad World 9 also provides visual summaries and exportable outputs for downstream analyses. It is especially valuable because it balances wide geographic coverage with clear component labels, making global patterns accessible to non-specialists while remaining useful for comparative population work. Like all model-based tools, it has limitations: proportions are model-dependent approximations, interpretation depends on the reference set and resolution, and it does not date admixture or identify specific recent relatives.
