[Genetic polymorphism of 17 Y-STR loci in four minority populations in Guangxi of China].
To investigate the genetic polymorphism of Y-chromosomal short tandem repeats (STR) loci in Jing, Yi, Yao, and Zhuang minority populations from Guangxi Province, China. 17 Y-STR loci were co-amplified using AmpFlSTR(R) Yfiler PCR Amplification Kit System, and the PCR products were analyzed by genetic analyzer. Cluster and phylogenic tree analyses were conducted to show the genetic distance among the populations. There were 61 different haplotypes in 100 unrelated Yao males, 67 in 105 unrelated Yi males, 79 in 103 unrelated Jing males, and 91 in 107 unrelated Zhuang males. The haplotype diversities of Jing, Yi, Yao and Zhuang were determined as 0.9784, 0.9866, 0.9911, and 0.9956, respectively. Among these 4 minority populations, the genetic distance between Jing and Zhuang was the smallest (0.0391), while the genetic distance between Yi and Yao was the largest (0.3376). The 17 Y-STR loci in the 4 minority populations from Guangxi Province revealed a highly polymorphic genetic distribution, which show a high potential for population genetics and forensic practice.
