About This Calculator

**Global Ancestry K23 — Modern, worldwide admixture calculator** Global Ancestry K23 estimates the proportional ancestry of an individual using 23 modeled components derived from 22 geographically and historically informed reference populations. It is built to detect fine-grained regional signatures across Eurasia, Africa, the Americas, and Oceania in the context of modern human population structure. What this calculator analyzes - Genome-wide allele frequency patterns to infer percentage contributions from 22 reference clusters (Anatolian, Baltic, Central-Europe, East-Balkan, East-Med, Eastern-European, Finnish, North-West-European, South-Central-Europe, West-Balkan, West-Med, East-African, North-African, West-African, Central-Asian, East-Asian, South-Asian, South-East-Asian, South-Caucasus, West-Asian, Siberian-Central-Amerindian, South-Amerindian). - Signals of recent and deep ancestry, distinguishing continental and sub-continental components. Who it’s designed for - Genealogy enthusiasts seeking regional breakdowns. - Researchers and students exploring recent population structure and admixture. - Individuals curious about how historical migrations shaped their genome across Eurasia, Africa, and the Americas. Insights you can gain - Percentage estimates of ancestral contributions from specific historical regions. - Detection of mixed heritage (e.g., Eurasian–African–Amerindian admixture) and likely geographic sources. - Clues to past migrations and contact events (Neolithic farmer expansions, Steppe ancestry pulses, Silk Road interactions, transatlantic movements). Historical and genetic context - Modern human populations reflect waves of migration, isolation and admixture: post-glacial recolonization, agricultural diffusion from Anatolia and the Near East, Bronze Age steppe movements, transcontinental trade and recent colonial-era gene flow. K23 frames individual genomes against these patterns using contemporary reference clusters. Why this calculator is

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 23 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

  • Your DNA is compared to 23 reference populations
  • Modern populations are used as genetic references
  • Results show your genetic similarity to these populations
  • More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

  • Results reflect genetic similarity, not direct ancestry
  • Modern populations are used as references
  • Percentages indicate relative genetic contribution
  • Results are estimates based on available reference data
