| Abstract: | Genetic variations of three populations(Liangzi Lake population of 19,Longwo Lake population of 19 and Huaihe River population of 18) of Plagiognathops microlepis were studied by sequence analysis of mitochondrial cytochrome b(Cyt b) gene.Gene fragments of 1149bp were acquired by PCR and DNA sequencing techniques.There were 10 haplotypes,116 nucleotide variable sites and 10.09% of nucleotide polymorphic loci among three populations of Plagiognathops microlepis.As a base composition,the content of A+T(about ... |
| Keywords: | Plagiognathops microlepis population genetic variation Cyt b gene |
