Abstract

Several diagnostic genetic markers were identified in Pomatoschistus marmoratus and P.tortonesei using polyacrylamide gel electrophoresis (PAGE) of allozymes. Twenty-one lociwere resolved, including the electrophoretic pattern of muscle proteins. The MDH*, PGM-1,2*, EST-1,2*, FUM* and PGI-2* loci exhibited different alleles which were fixed for thetwo species being analysed. Genetic distance, as calculated by Nei’s index, showed a value of0·413. Environmental hypersalinity, could have influenced the geographical distributionof P. tortonesei.
