Abstract

More than 2600 unrelated males from West-Europe were analysed by molecular hybridization experiments for the p49a,fTaq I polymorphisms. A total of 895 subjects (34%), belonging to haplogroup M269, were identified and further analysed for the three SNPs, S21/U106, S145/L21 and S28/U152; these three SNPs define the Northwest, West and South European sub-haplogroups, respectively. These haplogroups showed quite different frequency distribution patterns within West-Europe, with frequency peaks in Northern Europe, in Brittany in France and in Northern Italy/Southern France.
