Abstract: Objective To determine the genetic polymorphism of 24 Y-STR loci haplotype and investigate its application value in legal physical evidence.Methods AGCU Y24 kit and 3130xl Genetic Analyzer were used to detect the distribution of 24 Y-STR loci including DYS391,DYS389Ⅰ,DYS439,DYS389Ⅱ, DYS438, DYS643, DYS456, DYS458, DYS437, DYS635, DYS448, DYS527a/b, Y-GATA-H4, DYS447, DYS19,DYS392,DYS522,DYS393,DYS388,DYS390,DYS385a/b and DYS444in 154 unrelated individuals of Dongxiang ethnic minority males in Gansu province of China.Results A total number of 153 haplo-types were detected in 154 samples, the haplotype diversity was 0.9915 and the discrimination power was 0.9940.Conclusion The 24 Y-STR loci system has high haplotype diversity and discrimination power.
