Assessment of genetic diversity of Clarias batrachus using RAPD markers in three water bodies of Bhopal.

ABSTRACT

To assess the extent of genetic diversity within and between three populations of the catfish, Clarias batrachus, an analysis for random amplified polymorphic DNA (RAPD) variations were carried out. Five out of ten random primers produced constant and reproducible pattern of RAPD products. These five primers produced 72 scorable DNA fragments out of which 68 (86.66%) were polymorphic. Populations showed significant differences in their degree of polymorphism. Differences however, were observed in the primers in producing similarities in the populations.
