Abstract
1. 1. The extent of divergence of duplicate gene expression was determined to enzyme and tissue, by Klebe's method, in three species from family Sciaenidae (Perciformes). 2. 2. In the multilocus isozyme systems studied (PGI, LDH, CK and s-MDH) non-divergent gene expression among all tissues is present in 28% of the set patterns, unidirectionally divergent in 22% and bidirectionally divergent in 50%. 3. 3. An analysis of the evolution of the expression of duplicate genes from primitive to advanced fishes, and an interrelation of the four enzymes in the metabolism are presented.
