About This Calculator
**Tolan K54 — High‑Resolution Modern Admixture Calculator**
Tolan K54 analyzes an individual's genome against a finely curated set of 55 modern reference populations to estimate regional ancestry at a high level of detail. Built as a K54 model for the modern era, it compares allele-frequency patterns to reveal proportional contributions from geographically and historically meaningful groups across Europe, the North Atlantic, the Mediterranean and adjacent regions.
Who it's for:
- Individuals worldwide seeking a detailed picture of their recent and regional ancestry
- Genealogists, genetic genealogists, and amateur historians tracking regional lineages
- Researchers and students exploring population structure and recent admixture patterns
What you gain:
- A breakdown of ancestry proportions mapped to specific reference groups (e.g., Sweden, Sicily, Basque, Saami, Canary)
- Detection of fine-scale regional signals that standard continental tests may miss
- Context for interpreting migrations, local isolation, and admixture events in the recent millennia
Genetic and historical context:
The model reflects modern genetic structure shaped by events such as post‑glacial recolonization, Neolithic farming expansions, Bronze Age steppe movements, coastal and maritime gene flow, and localized drift in isolated or endogamous groups (e.g., Saami, Basque, island populations). Reference populations include northern, central and southern European clusters plus Atlantic island and Iberian groups to capture fine distinctions.
Why Tolan K54 is valuable:
- High resolution: many small, geographically specific references let you see subtle regional contributions
- Curated modern references: designed for current (modern era) comparative interpretation
- Practical: useful for genealogy, exploratory research, and educational insight into how recent historical processes shaped your DNA
Limitations and guidance:
Tolan K54 estimates are probabilistic, meant to inform not define identity.

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 54 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
- Your DNA is compared to 54 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
