Genetic polymorphisms for 11 Y-STRs haplotypes of Chinese Yi ethnic minority group.

Eleven Y-STRs loci including minimal haplotypes (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, and DYS385a,b) and two additional loci, namely DYS438 and DYS439 have been co-amplified in 100 healthy unrelated males of Chinese Yi minority ethnic group using the Y-PLEX 5 and Y-PLEX 6 kit, in order to investigate allele and haplotype frequencies of Yi population, evaluate their usefulness in forensic paternity testing and human identification, and enrich Chinese population genetic informational resources. Out of a total of 100 individuals 85 showed different haplotypes, while 8 haplotypes occurred more than once. The overall haplotype diversity for 11 Y-STRs loci was 0.9945.
