During which phase of meiosis are chromatids pulled to opposite poles of the cell?

Anaphase II
C
Telophase II
D
Anaphase I
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 Anaphase I of Meiosis I, homologous chromosomes (each consisting of two sister chromatids) are pulled to opposite poles of the cell. However, the sister chromatids remain attached at this stage.
In Meiosis II, the process resembles mitosis. During Anaphase II, the sister chromatids are finally separated and pulled to opposite poles of the cell.
Recognize that the separation of sister chromatids is a key event in Anaphase II, distinguishing it from Anaphase I where homologous chromosomes are separated.
Conclude that the phase of meiosis where chromatids are pulled to opposite poles of the cell is Anaphase II.
