Modern World K5

Modern World K5 is a five-component genetic admixture calculator that estimates proportions of contemporary ancestry across broad, globally distributed reference clusters: AMERINDIAN-SIBERIAN, ASIAN, EUROPEAN, WEST-ASIAN, and AFRICAN. Built for anyone curious about their genetic origins—consumers, genealogists, population geneticists, students, and community historians—this tool translates genome-wide allele patterns into a concise profile that reflects major continental contributions in the modern era. The calculator uses allele-frequency–based admixture modelling calibrated to modern reference panels. For each input genotype it returns a percentage breakdown among the five reference groups, enabling users to see dominant and minor components, assess complex mixed backgrounds, and compare individuals or samples at a glance. Because the model is trained on contemporary populations, it is especially sensitive to recent and historical admixture events (colonization, migration, trade, and diaspora) that shape present-day genomes. Context matters: the five components represent broad, geographically overlapping ancestries rather than discrete ethnic labels. AMERINDIAN-SIBERIAN captures Native American and northern Eurasian affinities; ASIAN reflects East and Southeast Asian diversity; EUROPEAN and WEST-ASIAN separate major West Eurasian clines; AFRICAN covers sub-Saharan diversity. The calculator illuminates large-scale demographic processes—such as transcontinental migrations and local admixture—while intentionally avoiding overprecision about fine-scale origin or timing. Why use Modern World K5? It provides a clear, interpretable first-pass overview of genetic ancestry that complements documentary genealogy and historical research. It is valuable for exploratory analysis, classroom demonstrations, and population-level comparisons. Users should note inherent limitations: results depend on reference choices and statistical modelling, cannot substitute for detailed reg
