ABSTRACT: A total of 2 548 unrelated healthy father-son pairs from a Northern Han Chinese population were genotyped at 41 Y chromosomal short tandem repeat (Y-STRs) including DYS19, DYS388, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS444, DYS447, DYS448, DYS449, DYS456, DYS458, DYS460, DYS481, DYS518, DYS522, DYS549, DYS533, DYS557, DYS570, DYS576, DYS593, DYS596, DYS627, DYS635, DYS643, DYS645, Y-GATA-H4, DYF387S1a/b, DYF404S1a/b, DYS385a/b, and DYS527a/b. In 2 548 father samples, 2 387 unique haplotypes were detected with the haplotype diversity and discrimination capacity values of 0.999 956 608 and 0.96 741 007. The average gene diversity (GD) value was 0.6934 with a range from 0.1051 at DYS645 to 0.9657 at DYS385a/b. When comparing alleles at 24 overlapped Y-ST
