In order to develop a genetic structure characterization, this study analyzed the Y-chromosome diversity of 558 males residing in 7 regions of France.
Abstract
From a total of 27 binary markers typed in the 7 regions, 22 different haplogroups were found. The most frequent haplogroup in all the regions was R1b1b2*(xR1b1b2a1, 2d, 2e, 2g), with the exception of the Alsace region, where the most common one was R1b1b2a2g. Seven of the haplogroups were found in all the populations analyzed, and four of them were only present in one or two individuals belonging to one population. Most of the samples showed haplogroup diversity values between 0.8 and 0.9, with the exception of the Bretagne region, which showed the most reduced value, with only 10 haplogroups present and 68.7 percent of the individuals belonging to the same haplogroup, R1b1b2. The haplogroup diversity in this region could be explained by a founder effect, followed by an isolation process for this population over time. In addition, Bretagne has lived several historical circumstances that involved waves of migrations, with major ones coming mostly from the British Isles. Also, Breton belongs to the same Brythonic branch of the Insular Celtic languages. This diversity should be considered when establishing general population databases. 4 tables, 3 figures, and 44 references
