During which phase of Meiosis II does crossing over occur?
A
Anaphase II
B
Crossing over does not occur in Meiosis II
C
Prophase II
D
Metaphase II
Verified step by step guidance1
Understand that crossing over is a process where homologous chromosomes exchange genetic material, increasing genetic diversity.
Recall that crossing over occurs during Prophase I of Meiosis I, not during Meiosis II.
In Meiosis II, the sister chromatids are separated, but no new genetic material is exchanged between chromosomes.
Review the phases of Meiosis II: Prophase II, Metaphase II, Anaphase II, and Telophase II, noting that these stages do not involve crossing over.
Conclude that crossing over does not occur in any phase of Meiosis II, as it is specific to Prophase I of Meiosis I.
