Genetic polymorphism of fifteen short tandem repeat loci in Chinese Drungs

Objective: To study the short tandem repeat (STR) polymorphism in Chinese Drungs (Tulungs). Methods: The genetic distributions of fifteen STR loci were investigated with the use of coamplification, genescan and genotype from 67 Drungs. Results: There were 144 STR alleles in Drung nationality, with their frequencies ranging from 0. 0077 to 0. 7846, heterozygosity (H) 0. 3723-0. 8639, discrimination power (DP) 0. 5567-0. 9548, probability of paternity exclusion (EPP) 0. 2738-0. 8358, polymorphism information content (PIC) 0. 3461-0. 8456, the accumulative DP 0. 99999998 and EPP 0. 99999894. Conclusion: The results of this study on the STR polymorphism in Chinese Drungs could be used as a basis for the genetic structure of Chinese ethnic groups and also be of significant application in anthropology and forensic science.
