Fig. 1

Karyotypes arranged from metaphase chromosomes of Clarias gariepinus (2n = 56), Clarias macrocephalus (2n = 54) and the natural hybrid of these species (2n = 55) after Giemsa staining and FISH with 18S rDNA (red) and 5S rDNA (green) probes. Note the intermediate level of distribution of the ribosomal sites in the hybrid specimen compared to the parental species. Scale bar = 5 μm
