Patterns of male-specific inter-population divergence in Europe, West Asiaand North Africa

We typed 1801 males from 55 locations for the Y-specific binary markers YAP ! DYZ3, SRY10831 and the (CA)n microsatellites YCAII and DYS413. Phylogenet ic relationships of chromosomes with the same binary haplotype were condens ed in seven large one-step networks! which accounted for 95% of all chromos omes. Their coalescence ages were estimated based on microsatellite diversi ty. The three largest and oldest networks undergo sharp frequency changes i n three areas. The more recent network; 3.1A clearly discriminates between Western and Eastern European populations. Pairwise Pst showed an overall in crement with increasing geographic distance but with a slope greatly reduce d when compared to previous reports. BI sectioning the entire data set acco rding to geographic and linguistic criteria, we found higher Fst-on-distanc e slopes within Europe than in West Asia or across the tno continents.
