Genetic Similarity Frequency and DNA Polymorphism between Common Carp and Israeli Carp Using Polymerase Chain Reaction-Random Amplified Polymorphic DNAs

Common carp (Cyprinus carpio) and Israeli carp(C. carpio) samples were obtained from a aquaculture facility in the Kunsan National University, Korea. Genomic DNA was isolated from the common carp and Israeli carp representing genetic characteristics and genomic polymorphisms by polymerase chain reaction amplification of DNA as arbitrary primers. There were observed a total of 90 species-specific genetic markers within Israeli carp. On average, each random RAPD primer produced amplified 7.9 products from 1 to 17 bands. An average genetic similarity within Israeli carp showed -.60$\pm$0.05. The average level of bandsharing was some 0.57$\pm$0.03 between common carp and Israeli carp. Accordingly, two carp species were genetically a little distant. The electrophoretic analysis of PCR-RAPD proudcts showed high levels of variation between two fish species. The RAPD polymorphism generated by primer may be used as a genetic marker for species or lines identification in important aquacultural carp.
