Abstract:
Objective To study the genetic polymorphism of 10 Y-chromosome STR loci by the allelic frequencies and haplotype frequencies in a Mongolia population sample of Baotou city.Methods We used PCR and polyacrylamidedel electrophoresis(PAGE) following silver staining to analyze the blood sample from the 99 unrelated Mongolia male individuals.Results The allele diversity values for each locus ranged from 0.458(DYS462) to 0.727(DYS389Ⅰ,DYS389Ⅱ) and gene diversity was above 0.5 except DYS462(0.458) in DYS392,DYS438,DYS439,DYS456,DYS459,DYS460, DYS461,DYS462,DYS389Ⅰ and DYS389Ⅱ loci.Furthermore,98 haplotypes were found from 10 loci and haplotype diversity was 0.98.Conclusion The haplotypes of the 10 Y-STR loci have the higher genetic polymorphism.
