Who are Swiss French?
Swiss French are the French-speaking population of Switzerland, especially associated with cantons such as Vaud, Geneva, Neuchatel, Jura, Fribourg, and Valais. Their history sits between the western Alps, the Lake Geneva region, Burgundy, Savoy, France, and the Swiss Confederation.
French is the main language, with regional Swiss features in speech and identity. Swiss French should be read as a western Alpine and Romandy reference rather than simply as broad French or broad Swiss German.
As a genetic reference, Swiss French is useful for comparison with Aosta Valley, Auvergne-Rhone-Alpes, Savoie, Burgundy-Franche-Comte, Provence, Marseille, French, Occitanie, Swiss German, Swiss Italian, and Alpine/western French references.
What is Swiss French DNA closest to?
In the World Genetics modern G25 table, Swiss French is closest to Italian Aosta Valley Valdotain, French Auvergne-Rhone-Alpes Puy-de-Dome, French Auvergne-Rhone-Alpes Ardeche, French Auvergne-Rhone-Alpes Savoie, French Bourgogne-Franche-Comte Saone-et-Loire, French Provence-Alpes-Cote d'Azur, French Auvergne-Rhone-Alpes Drome, French Provence-Alpes-Cote d'Azur Bouches-du-Rhone Marseille, French, and French Occitanie Haute-Garonne. The result places Swiss French in a western Alpine and southeastern/central French comparison space.
