  Current Y chromosome research is limited in the poor resolution of Y
chromosome phylogenetic tree. Entirely sequenced Y chromosomes in numerous
human individuals have only recently become available by the advent of
next-generation sequencing technology. The 1000 Genomes Project has sequenced Y
chromosomes from more than 1000 males. Here, we analyzed 1000 Genomes Project Y
chromosome data of 1269 individuals and discovered about 25,000 phylogenetic
relevant SNPs. Those new markers are useful in the phylogeny of Y chromosome
and will lead to an increased phylogenetic resolution for many Y chromosome
studies.
