Modern World K4

Modern World K4 is an admixture calculator that estimates the proportional ancestry components of individuals using four broad reference clusters: ASIAN, AFRICAN, AMERINDIAN‑SIBERIAN, and EUROPEAN‑WESTASIAN. Designed for a global audience, it is optimized for modern DNA datasets and intended for genealogists, population geneticists, adoptees, historians, and curious individuals who want a high‑level, interpretable snapshot of their genetic affinities. The calculator analyzes genome‑wide genotype data to assign fractions of an individual’s ancestry to each reference group, then presents those results as percentages, confidence ranges, and easy‑to‑read visual summaries. By comparing your genotype to these four continental and transcontinental references, Modern World K4 highlights major ancestral contributions shaped by millennia of migration, trade, and demographic change: African diversity and the Atlantic and trans‑Saharan dispersals; Asian expansions across East, South, and Southeast Asia; Amerindian and Siberian legacies reflecting the peopling of the Americas via Beringia; and the complex European–West Asian corridor influenced by Neolithic farmers, steppe migrations, and later mobility. The output helps users identify broad patterns — e.g., predominant continental ancestry, admixed profiles, recent versus older admixture signals — and offers historical context that links genetic signatures to known population movements. This tool is valuable because it provides a clear, accessible starting point for exploring ancestry without overwhelming technical detail. It is most useful as a comparative, educational resource or as a first pass that can guide deeper analyses with finer‑scale reference panels. Users should note that K4’s four‑cluster model simplifies continuous variation and is sensitive to reference selection; it does not measure cultural identity or predict traits. When used as part of a broader research or personal investigation, Modern World K4 delivers
