The events that occur during the anaphase of meiosis are "sister chromatids separate and migrate toward opposite poles".
Açıklamak
## Step 1<br />The problem is asking us to identify the events that occur during the anaphase of meiosis. Meiosis is a type of cell division that reduces the number of chromosomes by half, resulting in four haploid cells. It consists of two stages: Meiosis I and Meiosis II.<br /><br />## Step 2<br />The first event mentioned is "nuclear membranes re-form". This event actually happens during the telophase, not the anaphase. In the telophase, the chromosomes arrive at the poles, and two new nuclear membranes begin to form around each set of chromosomes.<br /><br />## Step 3<br />The second event is "sister chromatids separate and migrate toward opposite poles". This is indeed what happens during the anaphase. The sister chromatids, which are now individual chromosomes, are pulled apart by the spindle fibers and move towards opposite poles of the cell.<br /><br />## Step 4<br />The third event is "the cell is diploid". This is not an event that happens during the anaphase. A diploid cell is one that contains two sets of chromosomes, which is the case before meiosis begins. However, the anaphase is part of the process of meiosis, which reduces the number of chromosomes by half, resulting in haploid cells.<br /><br />## Step 5<br />The fourth event is "homologous chromosomes separate and migrate toward opposite poles". This event happens during the anaphase of Meiosis I, not the anaphase of Meiosis II. In Meiosis I, homologous chromosomes (each consisting of two sister chromatids) separate and move to opposite poles.
