RAPD-evaluated Genetic Polymorphisms and Relations among three River Nile Catfish (Siluriformes) Species from Qena, Egypt

Abstract

INTRODUCTION Genetic variation (polymorphisms) caused by mutational alterations are necessitated for species survival and adaptations in diverse environmental conditions (Fisher, 1930).The patterns of genetic discrepancy to species level can be exposed using tools of molecular genetic markers (Linda and Paul, 1995). Such information of molecular markers-based on decipherable polymorphism at DNA and protein levels are source of knowledge for several research applications including molecular ARTICLE INFO
