Y-chromosome DNA haplotypes in Basques.

One Y-specific DNA polymorphism (p49/ TaqI) was studied in a sample of 97 French Basques and compared with those found in 7 other French, Iberian, and Italian populations. A particularly high frequency (72.2%) of Y-haplotype XV was observed in Basques, compared to values (mean of 41%) obtained in other Western Europeans. Basques were also characterized by virtual absence, or presence at a low level, of the South or Near Eastern haplotypes XII, VII, and VIII. Considered together, these results confirm that Basques are a very ancient European population which has had little previous contact with the Neolithics.
