    Abstract: Biallelic polymorphisms on the Y chromosome have been extensively used to study the history, evolution, and migration patterns of world populations. In this study we screened 8.5 kb of Y chromosomal DNA for single nucleotide polymorphisms (SNPs) in a panel of 95 male individuals belonging to different haplogroups. Five novel Y-SNPs (PK1-5) were identified, four in the Pakistani sample and one in an African sample. The ancestral state of each SNP was determined in two chimpanzee samples and a variety of Pakistani ethnic groups. In addition to these novel Y-SNPs 77 additional markers on the Y chromosome were analyzed to place the SNPs on the phylogenetic tree of Y chromosomal lineages and to further investigate extant human Y chromosomal variation within Pakistan. BATWING analysis gave an estimate of between 2,500 and 7,300 YBP for population expansion in Pakistan which coincides with the period of the Indus Valley civilizations.
