New binary polymorphisms reshape and increase resolution of the human Y chromosomal haplogroup tree.
TLDR
Major changes in the topology of the parsimony tree are described and names for new and rearranged lineages within the tree following the rules presented by the Y Chromosome Consortium in 2002 are provided. Expand
Dual origins of the Japanese: common ground for hunter-gatherer and farmer Y chromosomes
TLDR
Coalescent analyses of Y chromosome short tandem repeat diversity indicated that haplogroups D and C began their expansions in Japan ∼20,000 and ∼12,000 years ago, respectively, while haplogroup O-47z began its expansion only ∼4,400 years ago. Expand
High-resolution SNPs and microsatellite haplotypes point to a single, recent entry of Native American Y chromosomes into the Americas.
TLDR
The hypothesis of a single migration of a polymorphic founding population better fits the expanded database and traced both lineages to a probable ancestral homeland in the vicinity of the Altai Mountains in Southwest Siberia. Expand
A recent bottleneck of Y chromosome diversity coincides with a global change in culture.
TLDR
A study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples, infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky, and hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.

High Levels of Y-Chromosome Differentiation among Native Siberian Populations and the Genetic Signature of a Boreal Hunter-Gatherer Way of Life
TLDR
The Siberian pattern of reduced haplogroup diversity within populations combined with high levels of differentiation among populations may be a general feature characteristic of indigenous groups that have small effective population sizes and that have been isolated for long periods of time. Expand
Major east-west division underlies Y chromosome stratification across Indonesia.
TLDR
A four-phase colonization model is put forward in which Paleolithic migrations of hunter-gatherers shape the primary structure of current Indonesian Y chromosome diversity, and Neolithic incursions make only a minor impact on the paternal gene pool, despite the large cultural impact of the Austronesian expansion. Expand
Genome-wide patterns of population structure and admixture among Hispanic/Latino populations
TLDR
The results suggest future genome-wide association scans in Hispanic/Latino populations may require correction for local genomic ancestry at a subcontinental scale when associating differences in the genome with disease risk, progression, and drug efficacy, as well as for admixture mapping. Expand
Forensic value of 14 novel STRs on the human Y chromosome.
TLDR
These novel short-tandem-repeats on the Y chromosome greatly improved the resolution of paternal lineages, above the level obtained with commonly used Y-STRs, in the European-American population. Expand
An African American paternal lineage adds an extremely ancient root to the human Y chromosome phylogenetic tree.
TLDR
The discovery of an African American Y chromosome that carries the ancestral state of all SNPs that defined the basal portion of the Y chromosome phylogenetic tree is reported, which exceeds current estimates of the mtDNA TMRCA, as well as those of the age of the oldest anatomically modern human fossils. Expand
Contrasting patterns of Y chromosome variation in Ashkenazi Jewish and host non-Jewish European populations
TLDR
It is striking that whereas Ashkenazi populations are genetically more diverse at both the SNP and STR level compared with their European non-Jewish counterparts, they have greatly reduced within-haplogroup STR variability, especially in those founder haplogroups that migrated from the Near East.
