Abstract: Objective To study the forensic application of G oldeneyeTM D N A ID 26Y K it in the She na-tionality. Methods Through capillary electrophoresis, the genotype of 26 Y-STR loci were analyzed in 53 unrelated m ale individuals from Fujian She nationality. The population genetics param eters such as allele frequency and haplotype diversity were calculated. The com parisons am ong the She nationality and the other nationalities were analyzed. Results A total of 126 alleles were observed on the 26 Y-STR loci of 53 unrelated m ale individuals. The allele frequencies and G D value ranged from 0.010 1 to 0.886 8 and 0.211 2 to 0.846 2, respectively. The G D value w as greater than 0.5 in the 19 loci. A total of 47 hap-lotypes were observed. B ased on RST, m ultidim ensional scaling plot indicated that the genetic relationship am ong Fujian She nationality and M innan H an nationality w as closest, follow ed by Southern C hina H an nationality and N orthern C hina nationality. Conclusion G oldeneyeTM D N A ID 26Y K it including 26 Y-STR loci has good polym orphism in the She nationality. A s an additional system , it has forensic appli-cation value in som e special cases.
