Abstract
Objective To investigate the polymorphism of 18 short tandem repeats (STR) loci of Qiannan Han population.Methods Using domestic DNATyperTM19 fluorescent labeling kit, and combining with PCR amplification and automated fluorescent detection of capillary electrophoresis, we carried out the DNA typing of 18 STR loci of 1, 104 unrelated individuals of Han population from Qiannan in Guizhou, China, and conducted statistical analysis to calculate the distribution of allelic frequency and other population genetics data.Results Genotypes of the 18 STR loci were in line with Hardy-Weinberg equilibrium (P > 0.05). Statistical analysis showed that the population genetics parameters of the 18 STR loci were as follows: heterozygosity (H) ranging from 0.622 to 0.915, matching probability (Pm) 0.017 to 0.220, power of discrimination (DP) 0.780 to 0.983, polymorphism information content (PIC) 0.540 to 0.900, and power of exclusion (PE) 0.318 to 0.826. In the 18 STR loci, the polymorphism indicators of PentaE were the highest, but those of the three of D3S1358, TH01 and TPOX the lowest.Conclusions This investigation demonstrates that allelic frequency of these 18 STR loci is well-distributed and high of polymorphism in Qiannan Han population.
