Résumé

Among members of the fish family Cyprinidae,a diploid—tetraploid relationship exists. The present study on electrophoretic patterns of 6-phosphogluconate dehydrogenase indicates that such diploid members as Barbus tetrazonamaintain allelic polymorphism at a single gene locus for this enzyme. Tetraploid members such as the carp and goldfish are endowed with two separate gene loci for 6-PGD. Tetraploid evolution apparently fixed two former alleles of the same locus as two separate gene loci. Furthermore, it appears that after becoming tetraploid, the carp and goldfish developed a separate regulatory mechanism for each locus; thus preferential activation of one or the other 6-PGD locus occurs in different tissues of tetraploid species.
