Abstract

Here we studied the genetic polymorphism and evolutionary differentiation of the Guangdong Liannan Yao population based on 15 autosomal STR loci and 19 Y chromosomal STR loci. The blood card DNA of 302 unrelated individuals from the Yao Autonomous County of Liannan was directly amplified using an Expressmarker 16 + 19Y kit and genotyped using a 3500XL Genetic Analyzer. For the autosomal STR loci, the CPD value was over 0.999 999 999 999, while the CPE value was over 0.9999. The population comparison revealed a closer relationship between the Liannan Yao population and the She ethnic population than other reported Chinese populations. For the Y-STRs, a total of 102 unique haplotypes were obtained, 87 of which were observed only once. Both R pairwise analysis and a multidimensional scaling plot showed that the Liannan Yao population is closely related to the Fujian She ethnic population and is significantly different from other Chinese ethnic populations. The results show that the 15 autosomal STR and 19 Y-STR loci are valuable for forensic applications and human genetic studies in the Liannan Yao population.

摘要

本研究基于 15 个常染色体 STR 基因座和 19 个 Y 染色体 STR 基因座，对广东连南瑶族群进行了遗传多态性和进化分化研究。使用 Expressmarker 16+19Y 试剂盒直接扩增来自连南瑶族自治县 302 名无关个体的血卡 DNA，并使用 3500XL 遗传分析仪进行基因分型。对于常染色体 STR 基因座，CPD 值超过 0.99999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999
