About This Calculator
World K43 (Updated: March 2024) is a curated, high‑resolution genetic admixture calculator that analyzes an individual's autosomal DNA and estimates proportional ancestry across 44 modern and regional reference populations. Using a carefully selected reference panel that spans Europe, Africa, the Middle East, South and Southeast Asia, Central and Northern Asia, East Asia, Oceania, and the Americas, the calculator decomposes your DNA into refined regional components to reveal continental and subcontinental signals and mixed heritage patterns.
Designed for genealogists, adoptees, ancestry enthusiasts, population geneticists, anthropologists, and curious users worldwide, World K43 is especially useful for anyone seeking more granular resolution than broad continental assignments. The report gives percentage breakdowns by reference cluster, highlights dominant regional affinities, and points out minor components that may indicate historical migrations, recent admixture, or shared deep ancestry.
Context matters: the 44 reference populations include groups such as Anatolia and the Caucasus, Basque and Northern Iberia, North and West African clusters, multiple West, Central and Southern African groups, Persian and Iranian clusters, multiple South and Southeast Asian sources, East Asian clusters, Melanesian and Polynesian components, and several Native American groups. These clusters mirror real historical processes — for example, farming expansions, steppe movements, the Bantu expansion, Austronesian dispersals, and long‑distance trade and migration — but assignments are modelled estimates and should be interpreted alongside historical, archaeological, and genealogical evidence.
Why this calculator is valuable: it offers a transparent, curated reference set and modern algorithmic handling to provide insightful, interpretable results at a fine regional scale. It helps refine family-tree hypotheses, contextualize DNA matches, and support research into population history.

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
