Description
Tolan K71 is a modern-era, high-resolution genetic admixture calculator designed to estimate the proportional ancestry of any individual using a broad, globally distributed set of 71 reference populations. It compares an individual’s genotype to finely resolved population clusters — with unusually dense coverage across Europe (Nordic, British Isles, Iberia, Italy, Balkans, Eastern Europe, Saami, Basque, Sardinia, Corsica and many regional subdivisions) as well as reference groups spanning the Caucasus, Iran & Assyria, Levant, Arabia, North and Sub‑Saharan Africa, Central and South Asia, China and Japan, Siberia, Southeast Asia, Oceania and the Americas.
Who it’s for: researchers, genetic genealogists, clinicians doing population-aware analyses, and curious individuals worldwide who want a nuanced view of ancestral composition. The calculator returns proportional ancestry estimates and highlights the closest reference affinities so you can see both major components and subtler minority contributions.
What you gain: a clear, interpretable breakdown of ancestral components that reflects both recent gene flow and older regional affinities. Because Tolan K71 includes many neighboring and historically distinct European subpopulations plus global comparators, it excels at distinguishing fine-scale European structure and at identifying low-frequency inputs from distant regions. Users can explore patterns consistent with historical migrations, trade routes, and demographic events while being guided to combine genetic results with historical and genealogical records.
Why it’s valuable: Tolan K71 balances breadth and resolution — wide global coverage for world-scale context, plus dense regional sampling for detailed local inference. It is a practical tool for hypothesis generation, quality control of ancestry calls, and for enriching personal or academic narratives about population history. As with any admixture analysis, results are estimates based on reference sampling

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 71 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 71 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
