title: Haplotype data for 23 Y-chromosome markers in four U.S. population groups.
abstract: The PowerPlex Y23 kit contains 23 Y-chromosomal loci including all 17 of the markers in the Yfiler Y-STR kit plus six additional markers: DYS481, DYS533, DYS549, DYS570, DYS576, and DYS643. We have typed 1032 unrelated population samples from four self-declared US groups: African Americans, Asians, Hispanics, and Western European Caucasians. An analysis of the population genetic parameters and the improvement of adding additional Y-STR markers to the dataset are described.
