Genetic variation among different morphotypes of the male freshwater prawn Macrobrachium rosenbergii (de Man)

The genetic differences between the blue claw male (BC), orange claw male (OC) and small male (SM) morphotypes of male freshwater prawns were assessed using microsatellite DNA markers. Thirty individuals from each of the three groups of male prawns were collected from a hatchery rearing system in Po...
