Multiple Choice
During anaphase II of meiosis, what is the key event that occurs in each cell?
A
Homologous chromosomes separate and move to opposite poles while sister chromatids remain attached.
B
Homologous chromosomes pair (synapse) and crossing over occurs between non-sister chromatids.
C
Sister chromatids separate at the centromeres and are pulled to opposite poles of the cell.
D
DNA replication occurs to produce identical sister chromatids before cell division.
Verified step by step guidance1
Recall the stages of meiosis, focusing on the differences between meiosis I and meiosis II.
Understand that during meiosis I, homologous chromosomes separate, which reduces the chromosome number by half.
Recognize that meiosis II resembles mitosis, where sister chromatids separate at the centromeres.
Identify that anaphase II specifically involves the separation of sister chromatids, which are then pulled to opposite poles of the cell.
Note that DNA replication does not occur between meiosis I and meiosis II, so the chromatids separated in anaphase II are the result of the original replication before meiosis began.
