A total of 2.4 kb frag-ment was amplified and subjected to restriction endonucle-ase analysis with nine restriction endonucleases subsequently.The results indicated that each subspecies owned one hyplo-type and four restriction enzymes (DdeⅠ, HaeⅢ, TaqⅠand MboⅠ) produced diagnostic restriction sites which could be used for discriminating the three subspecies and as molecu-lar genetic markers for assistant selective breeding of com-mon carp.展开更多
