Abstract

Objective To study the genetic polymorphism of 17 autosomal STR loci in the Jino people of Yunnan, and to evaluate its value in forensic medicine. Methods A total of 331 unrelated individuals of the Jino people in Yunnan Province were examined. AGCU 17+1 kit was used for STR genotyping, and ABI3130 capillary electrophoresis apparatus was used to isolate the amplified product fragments and to determineallele type . Results A total of 186 alleles were detected, and the allele frequencies ranged from 0.0015 to 0.561 9. TPOX and TH01 loci had the lowest polymorphism and recognition ability, and D3S1358, D13S317, D16S539, CSF1PO and D5S818 had poor polymorphism parameters. Other loci showed better polymorphism. The distribution of genotypes was in accordance with Hardy-Weinberg equilibrium, and CDP and CPE showed good recognition. Conclusion Except for TPOX and TH01, the remaining 15 autosomal STR loci have good polymorphism in Jino population, which can meet the application of forensic individual identification and paternity identification. Except the TPOX and TH01 loci, the remaining 15 autosomal STR loci have good polymorphisms in the Jino population.
- Forensic physical evidence,
