Abstract

Polyacrylamide gel electrophoresis was used to investigate the interspecific isozyme variability among three species of Porcellanid crabs: Petrolisthes ornatus, P. rufescens and P. boscii from the coastal waters of Karachi, Pakistan. Seven enzyme systems and the general protein (non-specific) were examined for genetic variations. Among the three species; Nei's heterozygosity for overall loci was observed (0.067), whereas Shannon’s information Index (I) for genetic variations based on the heterozygosity was (0.055) in three species of Genus Petrolisthes. Species were differentiated from each other as Nei’s genetic distance ranged in between 0.0093- 0.0314. The genetic relationship among the three species of genus Petrolisthes similar from those inferred from morphological features.
