Heterochromatic markers obtained by C-banding on metaphase plates of Astyanax lacustris (a), A. fasciatus (b), and A. schubarti (c), and Hyphessobrycon anisitsi (d) and hybrids A. lacustris × A. fasciatus (e), A. lacustris × A. schubarti (f), and A. lacustris × H. anisitsi (g, h) after C-banding. The arrows indicate heterochromatic markers. In h, a metaphase with 51 chromosomes, the chromosome being completely heterochromatic, can be observed. Scale bar: 5µm.
