This first of two papers on ultrastructural observations of meiosis in the red alga Dasya baillouviana ( Gmelin) Montague describes stages of prophase I of meiosis. Although the five stages of prophase were originally derived from light microscopic studies, the same stages were utilized for this ...

Fig. 1. Stages of oogenesis and folliculogenesis in the mouse. Primordial germ cells (PGCs) divide mitotically giving rise to oogonia that populate the genital ridge. Around embryonic day 12.5–13.5, oocytes enter prophase I of meiosis, that includes the stages zyogotene, pachytene, and diplo...
