During meiosis, replication of chromosomes occurs in

Options

A. Prophase I
B. Prophase II
C. Telophase I
D. Interphase

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a 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. **Phases of Meiosis**:
- Meiosis I includes Prophase I, Metaphase I, Anaphase I, and Telophase I.
- Meiosis II includes Prophase II, Metaphase II, Anaphase II, and Telophase II.

3. **Chromosome Replication**:
- Chromosome replication is crucial for meiosis as it ensures that each daughter cell receives the correct number of chromosomes.
- Chromosome replication occurs during the S phase of the cell cycle, which is part of interphase.

4. **Identifying the Correct Phase**:
- In the context of the options provided (Prophase I, Prophase II, Telophase I, or Interphase), the correct answer is Interphase.
- Specifically, it is during the S phase of Interphase that all chromosomes are replicated, resulting in each chromosome consisting of two sister chromatids.

5. **Conclusion**: Therefore, the replication of chromosomes during meiosis occurs in **Interphase**.

**Final Answer**: Interphase
