摘要：

The chromosomes of the Conger conger and Echelus myrus (Anguilliformes: Teleostei), were analysed by conventional (C and Ag-NOR) and by replication-banding techniques. Both species had a diploid number of 38 and one chromosome pair with C-positive nucleolar organizer regions (NOR). These cytogenetic traits are mainly consistent with those recorded for anguilliform species in general. The replication-banding pattern allowed us to identify individual chromosome pairs, to detect different classes of chromatin, and to suggest chromosome evolutive mechanisms in these two species. The results confirm the superiority of replication patterns in resolving longitudinal differentiation of fish chromosomes, that is not generally possible from structural bands.
