WebEvents that occur during prophase of mitosis also occur during prophase I of meiosis. The chromosomes coil up, the nuclear membrane begins to disintegrate, and the centrosomes begin moving apart. The two chromosomes may exchange fragments by a process called crossing over. When the chromosomes partially separate in late prophase, until they ...
