A focused population profile of Breton, with modern genetic matches, ancestry modeling, and a World Genetics G25 heatmap.
Breton is included in the World Genetics modern G25 database as a reference population. This page uses that reference average to compare Breton with other modern populations in the database.
The label should be read as a population reference name rather than a complete description of every individual, family, language, region, or community history connected with Breton.
In the World Genetics modern G25 comparison, the closest non-self match for Breton is Breton Ille-et-Vilaine Rennes. Other nearby references include Dutch Limburg, Breton Morbihan, Flemish Belgium, and Anglo-American Texas. This gives the Breton profile its nearest modern genetic context inside the current reference database.

The ancestral breakdown below loads the best-fitting World Genetics calculator for the Breton average. It should be read as a model of deep ancestry components, while the closest-match table is the better guide to which modern populations are most similar in G25 space.
The heatmap gives the Breton profile a geographic shape. Warmer areas mark regions where available modern reference populations sit closer to the Breton average, while cooler areas represent more distant matches.
The closest non-self match in this World Genetics comparison is Breton Ille-et-Vilaine Rennes. Other nearby references include Dutch Limburg, Breton Morbihan, Flemish Belgium, and Anglo-American Texas.
In the current modern G25 reference set, Breton Ille-et-Vilaine Rennes is the closest listed match to the Breton average after removing Breton itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Breton G25 average, giving the closest-match results a geographic view.
