Abstract: Objective To establish a 29 Y-STRloci multiplex PC Rsystemfor investigating the genetic polymorphisms and to assess its application value in forensic science. Methods Amultiplex PC Rsystemw as established using a five color fluorescence labeling 29 Y-STRloci (DYS456, DYS389Ⅰ, DYS437, DYS447, DYS389Ⅱ, DYS438, DYS522, DYS460, DYS458, DYS622, DYS390, DYS392, DYS448, DYS449, DYS391, Y-GATA-H4, DYS388, DYS19, DYS385a/b, DYS527a/b, DYS393, DYS459a/b, DYS635, DYS439, DYS570 and DYS627) for multiple amplification and capillary electrophoresis. And its applicability w as validated w ith genetic polymorphismdata of 29 Y-STRof unrelated 2 000 male samples in Shandong Han population. Results Atotal of 1981different haplotypes of 2 000 individuals show ed genotype diver-sity betw een 0.370 0 and 0.965 4. The systemprovided stable and accurate typing w ith high sensitivity of 0.05 ng. It satisfied the needs of variety of routine biological samples. Conclusion The 29 Y-STRloci multiplex PC Rsystemcould be applied for actual cases and establishment of Y-STRdatabase. In addi-tion, it has great significance in forensic science practices and related research.
