Abstract

Objective: To reveal the allelic frequencies and haplotype frequencies of ten Y-chromosome short tandem repeats(STR) loci (DYS392, DYS438, DYS439, DYS456, DYS459, DYS460,DYS461, DYS462, DYS389I and DYS389II systems) in an Elunchun population sample.

Methods: PCR and polyacrylamidegel electrophoresis(PAGE) followed by silver staining were performed to analyze the blood samples from 102 unrelated Elunchun male individuals.

Results: The allele diversity values for each locus ranged from 0.418(DYS461) to 0.727(DYS389 I). Gene diversities were higher than 0.5 except DYS462(0.479) and DYS461 (GATAA7.2)(0.418). Furthermore, 101 haplotypes from 10 Y-chromosome STRs loci were found in the sample and a high haplotype diversity 0.99 was determined.

Conclusion: The above findings suggest that the ten Y-chromosome STR loci are valuable Y-specific markers for establishing Y-STR database, understanding human origin, paternity testing and personal identification.
