Objective: To investigate the polymorphism of DXS6801, DXS6809, DXS7423, DXS7424, DXS9902 five loci in Hebei Han population.
Methods: The PCR products were detected by the polyacrylamide gel electrophresis and DNA sequencing analysis.
Results: Among 114 irrelative males and 118 irrelative females from Hebei Han population, 31 alleles were found in the 5 loci. One hundred and one haplotypes of the male were detected and the haplotype diversity reached 0.9975.
Conclusion: The five loci are relatively abundant in polymorphic information for identification and paternity test. And the obtained data of Hebei Han population can be applied to the X-short tandem repeat genetic data bank.
