Verified by ExpertsC
In meiosis, crossing over takes place during Prophase-I at the pachytene stage, so statement is correct. In Metaphase-II, chromosomes align at the equator, while the separation and migration of sister chromatids occur during Anaphase-II, hence statement is incorrect. In Anaphase-I, homologous chromosomes move to opposite poles, while they line up at the equator during Metaphase-I, so statement is also incorrect. Therefore, the correct match is only Prophase-I with crossing over.
