| 摘 要： | 以线粒体DNA D-loop序列为分子标记,研究了采自雷公山和武陵山的尾斑瘰螈(Paramesotriton caudopunclatus)5个种群的遗传多样性.获得42个个体mtDNA D-loop区序列,长度为690 bp,其中有30个变异位点,由此定义了13个单倍型.5个种群中未出现共享单倍型的现象.尾斑瘰螈种群...

| Abstract: | We studied the genetic diversity of five populations of Paramesotriton caudopunclatus using D-loop sequence of mtDNA as a molecular marker.As a result,we obtained 690 bp long D-loop sequences of 42 samples from five populations collected from Leigongshan and Wulingshan.In the sequences,there were 30 variable sites.Based on these sites 13 haplotypes are defined.No shared haplotype was found among the five populations.P.caudopunclatus populations had high haplotype diversity and low nucleotide diversity.The r... |
