Haplotype XV of the Y-chromosome is the main haplotype in West-Europe

We have analyzed Y-chromosome variation in a large sample of males from Western Europe by surveying p49a,f TaqI polymorphisms. Haplotype XV (A3, Cl, D2, Fl, Il) is the main Y-chromosome haplotype in West Europe, with a Basque focus in Southwestern Europe. This study demonstrates that the geographic distribution of Y-chromosome variation for p49a,f TaqI haplotype XV reveals an important genetic identity for populations that live in the Occidental part of Europe.
