The correct Answer is:
To solve the question, we need to match the items in Column I with the correct items in Column II based on our knowledge of meiosis and the stages involved. Let's break this down step by step. ### Step 1: Analyze the first item in Column I (A. Synapsis) - **Definition**: Synapsis is the pairing of homologous chromosomes during prophase I of meiosis. - **Matching**: This process occurs during the zygotene stage of prophase I. - **Conclusion**: A matches with 2 (Zygotene). ### Step 2: Analyze the second item in Column I (B. Centromere split) - **Definition**: The splitting of centromeres occurs during anaphase when sister chromatids are pulled apart. - **Matching**: This specifically happens during anaphase II of meiosis. - **Conclusion**: B matches with 3 (Anaphase II). ### Step 3: Analyze the third item in Column I (C. The action of enzyme recombinase) - **Definition**: The enzyme recombinase is involved in the genetic recombination process during prophase I of meiosis. - **Matching**: This action is associated with the pachytene stage, where crossing over occurs. - **Conclusion**: C matches with 1 (Pachytene). ### Step 4: Analyze the fourth item in Column I (D. Centromeres do not split) - **Definition**: During anaphase I of meiosis, the centromeres do not split; instead, homologous chromosomes are separated. - **Matching**: This is characteristic of anaphase I. - **Conclusion**: D matches with 4 (Anaphase I). ### Final Matching - A → 2 (Zygotene) - B → 3 (Anaphase II) - C → 1 (Pachytene) - D → 4 (Anaphase I) ### Answer The correct option is: - A2, B3, C1, D4
