Metaphases of Hypostomus regani after FISH with the HrV probe: karyomorph A (a, b) and karyomorph B (c, d) a DAPI stained metaphases of karyomorph A and the arrows indicate pair 19 b merged image of metaphase showing intense fluorescent signals positive for HrV probe in the pair 19 (arrows) c DAPI stained metaphases of karyomorph B and the arrows indicate heteromorphic pair 19 d merged image of metaphase showing intense fluorescent signals positive for HrV probe in the heteromorphic pair 19 (arrows). Scale bar: 10µm.
