Mitotic chromosomes of Hydra magnipapillata after C- banding (A), Hydra oxycnida after routine staining (B), and Pelmatohydra oligactis after C- banding (C). C-bands are visible in the centromeric areas of the chromosomes. Karyograms of H. magnipapillata (D), H. oxycnida (E) and P. oligactis (F). Arrows indicate achromatic gaps.
