Comparative study of genetic biodiversity in carp fish (Cyprinous carpio)

Author(s): Bhutada SA
Abstract: In the present study the genetic variations in the two countries population viz. India and Iraq of the Common carp, Cyprinus carpio were analyzed by Random Amplified Polymorphic DNA (RAPD) markers and the protein polymorphism. According to RAPD analysis the percentage of gene similarity (s) and the gene diversity (h) estimates were 93.75% and 68.75% for the India respectively and the percentage of gene similarity (s) and the gene diversity (h) estimates were 83% and 50% for Iraq respectively indicating the existence of a relatively high level of genetic variation in the India and Iraqi river population. According to protein analysis, the genetic similarity (s) and the gene diversity (h) estimates were 100 % and 67% for the Indian population respectively. The genetic similarity indices and genetic distance values indicated that Indian-Iraq populations of some common carp were genetically closer and some were genetically diverse. The minimum genetic distance between the species indicated that population was a reproductive isolated population. The data suggest that the RAPD technique being able to screen more easily a larger part of the nuclear genome than allozymes. The common carp i.e. Cyprinus carpio present a classified case of a species in a highly active state of differentiation and evolution and genetic variation between Indian and Iraq population.
