Description
DNA Genics World K38 is a modern, high-resolution admixture calculator designed to decompose an individual's autosomal DNA into proportions that reflect ancestry across a globally diverse set of reference groups. Using a curated panel of 36 reference populations drawn from Europe, West Asia, Central and South Asia, East Asia, Africa, the Americas and Oceania, this tool estimates your genomic affinities and highlights the relative contribution of ancestral source populations. Who it’s for: genealogists, hobbyists, professional researchers and anyone curious about multi-regional ancestry. Whether you have family stories to test, suspect recent mixed heritage, or are studying broader population patterns, World K38 provides an accessible, research-aware snapshot of genetic origins. What it analyzes and what you learn: the calculator evaluates genome-wide allele patterns and returns percentage-based ancestry components tied to reference populations such as North-West European, Iberian, Middle Eastern, South Asian, East Asian clusters, multiple African groups, Native American branches, and Oceanian lineages. Output helps identify major ancestral streams, minor admixture signals, and likely regional affinities. Combined with dates from complementary tools, these proportions can suggest historical admixture events, migration pathways, or corroborate documentary family history. Historical and genetic context: modern human genomes are mosaics shaped by migration, isolation, and contact. World K38 reflects that complexity by using geographically and culturally informed reference groups; it highlights continuity and admixture—e.g., Mediterranean, Eurasian steppe, Saharan-to-Southern African, and Pacific dispersal patterns—while making clear the probabilistic nature of assignments. Why it’s valuable: World K38 balances resolution and interpretability—offering more nuanced regional detail than broad continental models while remaining user-friendly. It’s a practical tool for p

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 38 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Key Points
  • Your DNA is compared to 38 reference populations
  • Modern populations are used as references
  • Results show your genetic similarity to these populations

Understanding Your Results

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

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