A focused population profile of Southwestern Gipuzkoa Basques, their Spanish Basque regional background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Southwestern Gipuzkoa Basques are associated with the southwestern part of Gipuzkoa, a Spanish Basque region close to Navarre, Biscay, and the inland western Pyrenees.
Basque and Spanish are both important, with local histories tied to Gipuzkoan valleys, Navarre contacts, and the broader Basque-speaking region.
As a genetic reference, Basque Spain Gipuzkoa Southwest is useful for comparison with Basque Spain Navarre Northwest, Basque Spain Gipuzkoa Tolosa, Basque Spain Gipuzkoa Central, Basque Spain Biscay, Basque France Lower Navarre, broad Basque Spain, Basque Spain Navarre Roncal, French Nouvelle-Aquitaine Landes Chalosse, Basque France Labourd, Basque Spain Navarre Central-West, Basque France Soule, and Basque Spain Álava.
In the World Genetics modern G25 comparison, the closest non-self match for Basque Spain Gipuzkoa Southwest is Basque Spain Navarre Northwest. Other nearby references include Basque Spain Gipuzkoa Tolosa, Basque Spain Gipuzkoa Central, Basque Spain Biscay, and Basque France Lower Navarre. This gives the Basque Spain Gipuzkoa Southwest profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Southwestern Gipuzkoa Basque ancestry is best interpreted as core Spanish Basque, close to Navarre Northwest, Tolosa, Central Gipuzkoa, Biscay, Lower Navarre, and Roncal.
The heatmap should emphasize southwestern Gipuzkoa, Navarre, Tolosa, central Gipuzkoa, Biscay, Lower Navarre, Labourd, Landes Chalosse, and the western Pyrenees.
The closest non-self match in this World Genetics comparison is Basque Spain Navarre Northwest. Other nearby references include Basque Spain Gipuzkoa Tolosa, Basque Spain Gipuzkoa Central, Basque Spain Biscay, and Basque France Lower Navarre.
In the current modern G25 reference set, Basque Spain Navarre Northwest is the closest listed match to the Basque Spain Gipuzkoa Southwest average after removing Basque Spain Gipuzkoa Southwest itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Basque Spain Gipuzkoa Southwest G25 average, giving the closest-match results a geographic view.
