Fig. 1 in Conserved number of U 2 snDNA sites in Piabina argentea, Piabarchus stramineus and two Bryconamericus species (Characidae, Stevardiinae)

Fig. 1. Sequential metaphases of the chromosomal locations of U2 snDNA and 5S rDNA clusters using two-color FISH in species of the genera Piabina, Piabarchus and Bryconamericus. The arrows indicate the fluorescent signals. Note that, in P. stramineus, the two repetitive DNA are located adjacently on the same pair. Scale bar = 10 µm.
