WebFurther progression in meiosis doesn't occur until puberty at the earliest. Spermatogenesis in a human male, on the other hand occurs over a 64 day period. Since oocytes sit in prophase 1 for ~ 13-50 years, they will have a very different proportion of time spent in each phase. You can read about this in Costanza Physiology, chapter 10.
Web14 mrt. 2024 · Prophase 2 is the initial phase of the meiosis 2. Telophase 1 is followed by prophase 2. No interphase can be found between telophase 1 and prophase 2.
