Résumé

DNA measurements, the number of chromosomes and the analysis of individual gene loci revealed a diploid-tetraploid relationship among members of the fish family Cyprinidae. Intermediate DNA values in some diploid species of this family are interpreted as the result of regional duplications. However, the analysis of 8 different isoenzyme systems in these species always confirmed the presence of only the dioploid number of genes; this includes the gene for the enzyme 6-PGD which was erraneously reported to be duplicated. In the order Isospondyli, on the other hand, where a diploid-tetraploid relationship has likewise been established, the smelt, Osmerus esperlanus provides a clear example for the duplication of single genes. In this representative of the diploid group the genes for S-AAT and PGI are duplicated.
