Abstract
ObjectiveTo investigate genetic polymorphism of 18 STR loci on human chromosomes of Han population in Shijiazhuang.MethodsAllelic frequencies for 18 STR loci and genetic parameters for forensic purpose were calculated. ResultsNo deviations of allelic frequency from Hardy-Weinberg equilibrium expectations were observed (P>0.05). 198 alleles and 695 genotypes were gained. Allele frequencies varied between 0.002 and 0.545; heterozygosity (H) between 0.624 and 0.932; matching probability (Pm) between 0.016 and 0.189; power of discrimination (DP) between 0.811 and 0.984; polymorphism information content (PIC) between 0.580 and 0.910; power exclusion (PE) between 0.321 and 0.861. 12 off-ladder alleles of 8 STR loci were found.Conclusions18 STR loci of Han population in Shijiazhuang are with relatively high polymorphism, and suitable for forensic individual identiifcation, paternity testing, and relative research.关键词
