Similarity of frog and of salamander chromosome structure
Stage 4 chromosomes. There is apparently a single chromonema along which compound granules and chromomeres of varying shapes and sizes are firmly embedded or attached. These chromosomes were treated with 0.2 M NaHCOa to remove the lateral loops and reveal the chromonemata. Chromosome granules are attached to the paired chromonemata at homologous loci. Some matric coating is present. Mild acidification following carbonate treatment has removed most of the lateral loops.
