About This Calculator
Tolan Recent Ancestors Bretagne — Modern-era Admixture Calculator
This calculator analyzes recent genome-wide ancestry by comparing your autosomal DNA to 32 curated modern reference populations, with special resolution for Bretagne (Brittany) and neighboring regions. It estimates proportional contributions from populations such as Britain & Ireland, France, Normandie, Iberia, Scandinavia, Central Europe, Turkey, Levant, North Africa, Sub-Sahara and many others, giving a multi-layered snapshot of recent ancestral makeup.
Who it's for:
- Individuals worldwide seeking fine-resolution, recent-era ancestry estimates
- Genealogists, adoptees and family historians tracing regional roots
- Population geneticists and educators exploring modern admixture patterns
What you gain:
- A breakdown of ancestry proportions across 32 reference clusters
- Clues to recent migration and regional gene flow (e.g., Atlantic, Mediterranean, Northern European, and Eurasian signals)
- Enhanced discrimination of Northwest French (Bretagne/Normandie) components from neighbouring populations
- Context for interpreting surprising or mixed results and guidance on limitations
Genetic and historical context: Brittany is a crossroads of Atlantic and European history — Celtic migrations, medieval Norman movements, maritime trade and more recent mobility have left layered genetic signatures. This calculator uses allele-frequency comparison and supervised admixture approaches tailored to modern-era references, so it highlights recent continental and subregional ancestry rather than deep prehistoric lineages.
Why it’s valuable:
- Focused regional resolution: distinguishes Bretagne and Normandie contributions that are often conflated in broader calculators
- Practical for modern genealogical timelines: emphasizes admixture consistent with the last several centuries
- Transparent about scope and limits: provides robust, interpretable estimates while noting reference-panel bias and the inabi

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 32 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
- Your DNA is compared to 32 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
