Genetic Polymorphisms of 21 Autosomal STR Loci of Fujian Han Population / 法医学杂志

OBJECTIVE@#To investigate the genetic polymorphisms of 21 autosomal STR loci of Fujian Han population and evaluate the forensic application value of GlobalFiler Express kit.@*METHODS@#Amplified with GlobalFiler Express kit, DNA samples were obtained from 741 unrelated individuals of Fujian Han population. The population genetics parameters of 21 autosomal STR loci were calculated.@*RESULTS@#The 21 autosomal STR loci were found to be no deviation from Hardy-Weinberg equilibration (P > 0.05) and relatively abundant in high polymorphism. Heterozygosity ranged from 0.589 to 0.914, power of discrimination ranged from 0.754 to 0.992, polymorphic information content ranged from 0.520 to 0.940, and power of exclusion ranged from 0.278 to 0.825. The SE33 locus was the highest degree in polymorphism.@*CONCLUSION@#The 21 STR loci of GlobalFiler Express kit have high value in discrimination power and can be useful in personal identification and paternity test in Fujian Han population.

Applications of DNA identification technology in protection of wild animals / 法医学杂志

With the development of biotechnology, forensic DNA identification technology in protection of wild animals has been used more and more widely. This review introduces the global status of wildlife crime and the relevant protection to wildlife, outlines the practical applications of forensic DNA identification technology with regard to species identification, determination of geographic origin, individual identification and paternity identification. It focus on the techniques commonly used in DNA typing and their merits and demerits, as well as the problems and prospects of forensic DNA technology for wildlife conservation.
