Abstract:The variable number of tandem repeat(VNTR)of D17S30 locus in 270 unrelated individuals of She ethnic group was studied by polymerase chain reaction(PCR).The results showed that 12 alleles were detected and their sizes ranged from 168bp to 1 008bp.The allele frequencies were 0.0056~0.3259,the heterozygosity of this locus was 79.10% and the paternity exclusion probability was 0.4358.The number of D17S30 VNTR allele and allele frequency of She were different from those of Han ethnic group in Mendelian Law.Statistical analysis demonstrated that their geneotypes were consistent with Hardy-Weinberg equilibrium(x2=79.97,v=66,P=0.1158>0.05).
