Population genetics for Y-chromosonal STRs haplotypes of Chinese Korean ethnic group in northeastern China

Y-chromosomal STRs loci were analyzed from a sample of 201 healthy unrelated male individuals of Chinese Korean ethnic group. Allele and haplotype frequencies for DYS19, DYS385a/b, DYS388, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 were determined by the general PCR and silver staining methods. The gene diversity values for the Y-STRs loci ranged from 0.4146 (DYS437) to 0.9631 (DYS385a/b). A total of 194 haplotypes were identified in the Y-STR loci, among which 188 were unique, while 6 occurred more than once. And the combined haploytpes diversity was 0.9996. The results in the present study can be used for routine forensic application in the region, and enrich Chinese ethnical genetic informational resources. (C) 2007 Elsevier Ireland Ltd.
