Abstract:
French population, despite of its crucial geographic location for repopulation movements of Europe across time, it has been insufficiently characterized at the genetic level, especially for Y-chromosomal DNA variation. In order to make a genetic structure characterization, we have analyzed the Y-chromosome diversity of 558 male individuals, scattered along 7 different French regions: Alsace (Strasbourg), Auvergne (Clermont-Ferrand), Bretagne (Rennes), Île-de-France (Paris), Midi-Pyrénées (Toulouse), Nord-Pas-de-Calais (Lille) and Provence-Alpes-Côte d'Azur (Marseille). A total of 17 Y-chromosome STRs and 27 Y-chromosome SNPs were genotyped for each individual. Even though we find that most of the individual populations in France were not differentiated from each other, Bretagne population shows population substructure, an important fact to be considered when establishing general population databases.

Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....
