From: Karyotype diversity and evolutionary trends in the Asian swamp eel Monopterus albus (Synbranchiformes, Synbranchidae): a case of chromosomal speciation?

Fig. 3

Karyotypes of the two Asian swamp eel Monopterus albus karyomorphs analyzed by (a) conventional staining and C-banding and (b) fluorescence in situ hybridization (FISH) with 5S (green) and 18S (red) rDNA probes. Inserted boxes indicate NOR-bearing chromosomes and CMA3 positive chromosomes. In (c) idiograms highlight the distribution of 18S rDNA (red) and 5S rDNA (green) in both karyomorphs. In the middle, the panel label highlights the main rearrangements related to karyotype differentiations, where centric fusions have played a major role. Scale bar = 5 μm
