Analysis of genetic diversity in mystus guttatus from xijiang branch of pearl river
野生斑?西江地理群的遗传多样性分析
Cluster analysis by upgma methods indicated that these five stocks might be divided into three clusters . results of rapd a nalysis suggested that extensive genetic diversity was detected in this species and the genetic divergence among stocks was relatively high ; upgma phylogenetic tree showed there existed three geographic populations of p . polyactis in the yellow sea and the east china sea , which supported the previous conclusion by morphological and ecological methods . part two : the genetic diversity between trichiurus lepturus and eupleurogrammus muticus random amplified polymorphic dna ( rapd ) technique was applied to 12 individuals from each species of the hairtail fishes trichiurus lepturus and eupleurogrammus muticus collected from the yellow sea
