Admixture Calculator
Global Ancestry K43
Modern World K43 is a curated, modern-era admixture calculator that estimates ancestry across 43 global reference populations. Designed for genealogists, researchers, and curious users worldwide, it reveals fine-scale proportions reflecting migrations, trade, and regional mixture. Use it to explore recent genetic history with clear, interpretable results—while noting limitations tied to reference coverage and input quality.

About This Calculator
Modern World K43 is a curated, modern-era genetic admixture calculator designed to estimate the proportional ancestry of samples against 43 geographically and culturally informed reference populations from across the globe. It analyzes genome-wide genotype data to assign percentage contributions from fine-scale groups such as Northern Africa, West and Central African clusters, diverse South and Southeast Asian populations, multiple East Asian subgroups, a broad spectrum of European populations (including Basque, Sardinian, and Baltic clusters), Middle Eastern and Caucasus sources, Oceanian lineages, and two distinct Native American groupings. The tool is intended for worldwide users: genealogists, community researchers, population geneticists, educators, and curious individuals who want a deeper, structured view of recent and relatively recent ancestry patterns.
Modern World K43 highlights insights into admixture proportions that reflect migrations, trade, diasporas, and local demographic processes—from transcontinental movements to regional intermarriage. Because the reference set is curated to include closely related and historically meaningful populations, the calculator can distinguish subtle differences (for example, between Western and Eastern European components, or among Southeast Asian and Oceanian sources) that broader models may conflate. Results can help users contextualize family histories, support research hypotheses about population contact, and illustrate the geographic mosaic of modern human diversity.
Important context and limitations: Modern World K43 interprets genetic similarity relative to the chosen reference panel and is best understood as a probabilistic breakdown rather than a definitive identity label. Accuracy depends on the quality of input genotypes and how well a user's ancestral sources are represented among the reference populations. The calculator focuses on modern admixture signals and should be used alongside historical, archaeo

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 43 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
- Your DNA is compared to 43 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
