The correct Answer is:
To answer the question regarding the formation of the second spindle in Meiosis II, we will break down the process step by step. ### Step-by-Step Solution: 1. **Understanding Meiosis**: - Meiosis is a specialized type of cell division that reduces the chromosome number by half, resulting in four haploid cells. It consists of two main stages: Meiosis I and Meiosis II. 2. **Spindle Formation in Meiosis**: - During both Meiosis I and Meiosis II, spindle fibers are crucial for the separation of chromosomes. In Meiosis I, a single spindle apparatus is formed. 3. **Formation of the Second Spindle**: - In Meiosis II, after the first meiotic division is completed, a second spindle apparatus is formed. This occurs in the second meiotic division, which resembles mitosis. 4. **Orientation of the Second Spindle**: - The second spindle is formed at a right angle (90 degrees) to the first spindle. This means that if the first spindle is oriented vertically, the second spindle will be oriented horizontally. 5. **Conclusion**: - Therefore, the correct answer to the question is that the second spindle formed in Meiosis II is formed at a right angle to the first spindle. ### Final Answer: The second spindle formed in Meiosis II is formed **at a right angle to the first spindle**. ---
