N2 - A karyological study of four species of gobiid fishes, Gobius niger, G. paganellus, G. cobitis, and Zosterisessor ophiocephalus (Perciformes, Gobiidae), was conducted by standard, fluorochrome staining (using chromomycin A3, mithramycin, and DAPI), Alu-I digestion, and CBG- and RBG-banding methods. Our cytogenetic data indicate that heterochromatin in these taxa is highly differentiated, exhibiting heterogeneity in staining characteristics, and presumably in underlying DNA sequences, and a different capability for promoting Robertsonian fusions.
