Web25 okt. 2010 · In spite of evolutionary conservation of meiosis, many of the genes that control mammalian meiosis are still unknown. We report here that the ENU-induced repro4 mutation, identified in a screen to uncover genes that control mouse meiosis, causes failure of spermatocytes to exit meiotic prophase I via the G2/MI transition. Major events of … WebMitotic stages. The cell cycle, which includes interphase (A and 1) and mitosis, is a continuous process. Nevertheless a number of mitotic stages can be defined: prophase (B and 2), metaphase (C and 3), anaphase (mid 4 and late D and 5), telophase (E) and cytokinesis (F and 6). Completion of mitosis usually takes several hours.
