Dodecad K7b

Dodecad K7b is a modern, global admixture calculator that decomposes an individual's autosomal genotype into a compact set of ancestral components. Built on the Dodecad community framework and tuned for broad, cross-continental contrasts, the K7b model summarizes genetic variation into seven major ancestry signals while using a diverse set of world reference samples (including South Asian, West Asian, Siberian, African, Southern, Atlantic_Baltic, East Asian, Asian and European populations) to anchor and interpret those signals. Who it’s for: K7b is designed for enthusiasts, genealogists, population geneticists and students who want a clear, interpretable portrait of major ancestral influences in a worldwide context. It is especially useful for people with mixed backgrounds, researchers comparing population-level patterns, and anyone seeking a coarse-grained complement to more fine-scaled regional models. Insights you can gain: The calculator highlights proportional contributions from broad ancestral clusters, revealing major continental affinities (for example, West Eurasian, South Asian, East Asian, Siberian, and African-related ancestry) and the relative balance among them. Users can detect dominant deep ancestry, observe signals of historical admixture (e.g., Eurasian–African blends), and compare samples to global reference anchors. Context and limitations: Admixture models like K7b are simplifications that depend on reference choice and marker sets. K7b emphasizes broad, interpretable components rather than fine-scale local structure; it is not intended to pinpoint recent single-surname ancestors or precise geographic locales. Results are best used alongside historical, archaeological, and genealogical information. Why it’s valuable: By providing a concise, visualizable summary of major genetic influences, Dodecad K7b helps users orient themselves on the global genetic map, compare individuals and populations, and frame deeper investigations with higher-res
