Fig. 3From: Genomic organization of repetitive DNAs highlights chromosomal evolution in the genus Clarias (Clariidae, Siluriformes)Karyotypes arranged from metaphase chromosomes of Clarias gariepinus (2n = 56), Clarias macrocephalus (2n = 54) and the natural hybrid of these species (2n = 55) after FISH with (GA)15 and (CA)15 microsatellite probes. Note the weak distribution of both microsatellites in C. gariepinus, their strong accumulation in C. macrocephalus and the intermediate distribution pattern in the hybrid specimen.
