Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four daughter cells. It consists of two stages: Meiosis I and Meiosis II.
Recall that during Meiosis I, homologous chromosomes are separated, not sister chromatids. This is a key distinction from mitosis.
In Anaphase I, homologous chromosomes are pulled apart to opposite poles of the cell, but sister chromatids remain together.
Meiosis II is similar to mitosis, where the sister chromatids are finally separated. This occurs during Anaphase II.
Therefore, the phase of meiosis during which sister chromatids are separated is Anaphase II, as this is when they are pulled apart to opposite poles of the cell.
