Multiple Choice
During which stage of meiosis do homologous chromosomes separate from each other and move to opposite poles?
A
Anaphase I
B
Anaphase II
C
Metaphase I
D
Telophase I
Verified step by step guidance1
Recall the main stages of meiosis: Meiosis I and Meiosis II, each with Prophase, Metaphase, Anaphase, and Telophase phases.
Understand that during Meiosis I, homologous chromosomes (each consisting of two sister chromatids) pair up and then separate, while during Meiosis II, sister chromatids separate.
Identify that the separation of homologous chromosomes occurs specifically during Anaphase I, when the homologous pairs are pulled to opposite poles of the cell.
Recognize that Anaphase II involves the separation of sister chromatids, not homologous chromosomes.
Conclude that the correct stage for homologous chromosome separation is Anaphase I.
