About This Calculator

**Global Ancestry K23 2023** is a modern, high-resolution admixture calculator (K = 23) that analyzes autosomal genotype data to estimate the proportion of ancestral components drawn from a worldwide set of reference populations. It is built to identify continental- and subcontinental-level ancestry signals and to help users translate their DNA into geographic and historical context. What this calculator analyzes - Percent contributions of 23 reference populations across Africa, Europe, Asia, Oceania and the Americas - Broad and fine-scale ancestry signals that reflect recent and ancient admixture - Autosomal patterns that represent the combined inheritance from all ancestral lines Who this is designed for - Consumers exploring personal ancestry and ancestry enthusiasts - Genealogists and adoptees seeking biogeographic clues - Researchers and students who need a compact K=23 reference for comparative analyses Insights you can gain - A proportional breakdown of likely ancestral sources (e.g., West African, Near Eastern, South Asian, Melanesian, Native American) - Clues about past migrations and contact zones (e.g., Bantu expansions, Eurasian steppe movements, colonial-era admixture, Austronesian dispersals) - A clearer picture of multi-continental heritage and unexpected minor components Reference populations include: Benin Togo; Africa Southeastern Bantu; Cameroon Congo; Mali; Senegal; Africa North; Ivory Coast Ghana; Nigeria; Caucasus; Asia Central; Asia South; Near East; Asia East; Europe East; Finland Northwest Russia; Europe West; Iberian Peninsula; Great Britain; Italy Greece; Ireland; Scandinavia; Melanesia; Native American. Historical and genetic context - By comparing an individual to geographically and linguistically informed reference groups, the calculator frames ancestry in terms of major demographic events — migrations, trade routes, colonization, and long-term regional continuity. Why this calculator is valuable - Offers a balanced, interpretable

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
