AIIMS 2017 Botany Meiosis MCQ Question

Option B is correct because diakinesis is the final stage of prophase I in meiosis, where homologous chromosomes undergo crossing over, leading to the exchange of genetic material. This process increases genetic diversity in the resulting gametes.

Option A is incorrect as meiosis produces genetically diverse cells, not genetically similar ones. Option C is also incorrect because, while centromeric division occurs during anaphase II, it is not the defining feature of that stage; rather, it is the separation of sister chromatids that is crucial.
