ABSTRACT
In the present study, blood samples of 984 unrelated Han individuals were collected from Dongfang, Southern China, after informed consent. A total of 29 Y-chromosomal short tandem repeat (Y-STR) were analyzed, including DYF387S1, DYS19, DYS385ab, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS444, DYS447, DYS448, DYS449, DYS456, DYS458, DYS460, DYS481, DYS508, DYS518, DYS533, DYS576, DYS635, DYS643 and GATAH4. A total of 749 different haplotypes were found among 984 individuals, of which 645 were unique. The haplotype diversity was 0.9988 and the discrimination capacity was 0.7612, while the match probability was 0.0025. The smallest genetic distance (RST = 0.0155) was found between the Dongfang Han population and Guizhou Han population, while the largest genetic distance (RST = 0.1284) was observed with Gansu Tibetan.
