Genetic Polymorphism of 17 Y-STR Loci in Han Chinese Living in Lanzhou

摘要

The genetic polymorphism across 17 Y-STR loci in a population of Han Chinese in Lanzhou was investigated.Haplotypes and allele frequencies for the 17 Y-chromosomal STRs loci DYS456,DYS389I,DYS390,DYS389Ⅱ,DYS458,DYS19,DYS385a/b,DYS393,DYS391,DYS439,DYS635,DYS392,Y GATA H4,DYS437,DYS438 and DYS448 were determined in 500 healthy unrelated autochthonous males from Lanzhou.The results showed that no shared haplotypes were observed.Gene diversity values ranged from 0.3987(DYS391)to 0.9740(DYS385a,b).It was concluded that these loci will be very useful for human identification in forensic cases and paternity tests within the Han Chinese population inhabiting Lanzhou.
