Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.
These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift.
A Predominantly Neolithic Origin for European Paternal Lineages
Most present-day European men inherited their Y chromosomes from the farmers who spread from the Near East 10,000 years ago, rather than from the hunter-gatherers of the Paleolithic.
A comprehensive survey of human Y-chromosomal microsatellites.
A large number of new, highly polymorphic Y-chromosomal microsatellites are now available for population-genetic, evolutionary, genealogical, and forensic investigations.
Gene conversion between the X chromosome and the male-specific region of the Y chromosome at a translocation hotspot.
Patterns of inter- and intra-group genetic diversity in the Vlax Roma as revealed by Y chromosome and mitochondrial DNA lineages
The study unambiguously points to the common origins of the three Vlax groups and the recent nature of the population fissions, and provides preliminary evidence of limited genetic diversity in this young founder population.
High level of male-biased Scandinavian admixture in Greenlandic Inuit shown by Y-chromosomal analysis
Comparison of the European component of Inuit Y chromosomes with European population data suggests that they have their origins in Scandinavia, and the extreme sex bias in the admixture makes the later event more likely as the source.
Identification of a Y chromosome haplogroup associated with reduced sperm counts.
This study defines, for the first time, a class of Y chromosome that is at risk for infertility in a European population: haplogroup 26+, which was significantly overrepresented in the group of men with either idiopathic oligozoospermia or azoospermia compared to the control Danish male population.
High levels of sequence polymorphism and linkage disequilibrium at the telomere of 12q: implications for telomere biology and human evolution.
The data suggest that 12q telomeres, like Xp/Yp telomereres, exhibit low levels of homologous recombination and evolve along haploid lineages, and a model that involves the hybridization of two archaic hominoids lineages ultimately giving rise to modern Homo sapiens is proposed.
The Use of Y-Chromosomal DNA Variation to Investigate Population History
Y-chromosomal DNA lineages can be used to trace the origins of males in modern populations and microsatellite analysis shows that the diversity of haplogroup 3 chromosomes is low, suggesting a recent spread.

The observed mismatch distributions appear to reflect different underlying demographic histories and/or selective pressures for maternally and paternally transmitted loci, and the difference between the mismatch distributions inferred from mitochondrial and Y-chromosome data are not a statistical artifact.
