Polymorphisms on 15 STR loci of Han population in Yan'an / 中国医学科学院学报

<p><b>OBJECTIVE</b>To investigate the polymorphisms of 15 STR loci of Han population in Yan'an.</p><p><b>METHODS</b>Blood samples were obtained from 100 unrelated Han individuals in Yan'an. DNA templates were screened by AmpF/STR Identifiler kit and ABI3100Avant DNA analyzer.</p><p><b>RESULTS</b>The allele frequencies of 15 STR loci ranged from 0.005 to 0.550, and the genotype frequencies ranged from 0.010 to 0.310. The combined match probability was 2.5x10(-17) and combined EPP was 0.999999999.</p><p><b>CONCLUSIONS</b>The 15 STR loci used in this study were highly polymorphic in Han population in Yan'an and suitable for population study and forensic cases in this region.</p>
