Abstract/OtherAbstract:
Due to the very limited amount of knowledge available on the cytochemistry and architecture of fish chromosomes, an extensive banding study was carried out on chromosomes of the central mudminnow, Umbra limi. Through the use of fluorescent staining, C-banding, and silver staining, the chromosomes were characterized, and an idiogram was constructed showing the location of C-band heterochromatin, F-bodies, and the nucleolar-organizer regions. G-banding was attempted but was unsuccessful. Results of fluorescent staining with 33258 Hoechst and quinacrine HC1 raised some interesting questions concerning the cytochemistry of U. limi chromosomes, as well as the specificity of these stains.
