In an organism with \(n=2\), which phase of meiosis is shown last in the diagram?

• A. Anaphase I
• B. Telophase II
• C. Metaphase II
• D. Prophase II

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the context of meiosis. Meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It consists of two main stages: Meiosis I and Meiosis II, each with subphases (Prophase, Metaphase, Anaphase, and Telophase).
2. Step 2: Recall the sequence of events in Meiosis II. Meiosis II is similar to mitosis and includes Prophase II, Metaphase II, Anaphase II, and Telophase II. Telophase II is the final phase of meiosis, where the nuclear envelope reforms, and the cells divide completely.
3. Step 3: Analyze the options provided. The question asks which phase of meiosis is shown last in the diagram. The options include Anaphase I, Telophase II, Metaphase II, and Prophase II. Since Telophase II is the last phase of meiosis, it is the correct answer.
4. Step 4: Relate the phases to the organism with \(n=2\). In an organism with \(n=2\), meiosis will result in four haploid cells, each with one chromosome. Telophase II marks the completion of this process.
5. Step 5: Confirm the reasoning. Telophase II is the last phase of meiosis, regardless of the organism's chromosome number (\(n\)). This phase ensures the division is complete, and the haploid cells are formed.
