If chiasmata can be seen in a cell under a microscope,which of the following meiotic processes must have occurred?

Question

Quizplus · Accepted Answer

Chiasmata are structures that form during prophase I of meiosis when homologous chromosomes exchange genetic material through crossing over. Therefore, the correct choice is C, prophase I, because this is the only meiotic process where chiasmata occur. Meiosis II and anaphase II do not involve crossing over, and anaphase I occurs after chiasmata have already formed.
