Partial metaphases of Bradypus variegatus (2n = 54) after FISH with human chromosome-specific paints. The probes used are indicated for each experiment. The green signals were produced by biotin-labeled probes detected with FITC-conjugated avidin and the red signals, by digoxigenin-labeled probes detected with rhodamine-conjugated antidigoxigenin. The chromosomes were counterstained with DAPI.
