A focused population profile of Tolosa Basques from Gipuzkoa, their Spanish Basque background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Tolosa Basques are associated with Tolosa and surrounding areas of Gipuzkoa in the Spanish Basque Country, a core Basque-speaking region in the western Pyrenean-Atlantic zone.
Basque and Spanish are both important. Tolosa's position connects Gipuzkoa with Navarre, French Basque Country, Biscay, and the inland Basque valleys.
As a genetic reference, Basque Spain Gipuzkoa Tolosa is useful for comparison with Basque Spain Navarre Northwest, Basque France Lower Navarre, Basque Spain Gipuzkoa Southwest, Basque Spain Navarre Roncal, broad Basque Spain, Basque Spain Biscay, Basque France Soule, Basque France Labourd, Basque Spain Gipuzkoa Central, Basque Spain Navarre Central-West, broad Basque France, and French Nouvelle-Aquitaine Landes Chalosse.
In the World Genetics modern G25 comparison, Basque Spain Gipuzkoa Tolosa is closest to Basque Spain Navarre Northwest, Basque France Lower Navarre, Basque Spain Gipuzkoa Southwest, Basque Spain Navarre Roncal, broad Basque Spain, Basque Spain Biscay, Basque France Soule, Basque France Labourd, Basque Spain Gipuzkoa Central, and Basque Spain Navarre Central-West. The result places Tolosa in the tight Gipuzkoa-Navarre-French Basque cluster.
| Population | Distance |

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Tolosa Basque ancestry is best interpreted as core Gipuzkoan Basque, close to Navarre Northwest, Lower Navarre, Gipuzkoa Southwest, Roncal, Biscay, Soule, Labourd, and Central Gipuzkoa.
The heatmap should emphasize Tolosa, Gipuzkoa, Navarre Northwest, Lower Navarre, Roncal, Biscay, Soule, Labourd, and the western Pyrenees.
Yes. Basque Spain Navarre Northwest is the closest match.
Yes. Lower Navarre, Soule, and Labourd all appear very close.
Yes. Gipuzkoa Southwest and Gipuzkoa Central are both close matches.
