The homologous , chromosomes line up at the equator in pairs, name of phase and sequence

Options

A. metaphase of mitosis
B. metaphase of meiosis-1
C. both metaphase of meiosis
D. both (a) and (b)

Answer

To solve the question "The homologous chromosomes line up at the equator in pairs, name of phase and sequence," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chromosome Alignment**:
- In cell division, chromosomes undergo specific phases where they align and separate. The question specifies that homologous chromosomes are lining up at the equator in pairs.

2. **Identifying the Phase**:
- The alignment of homologous chromosomes at the equator occurs during a specific phase of meiosis. In meiosis, there are two divisions: Meiosis I and Meiosis II.
- In Meiosis I, homologous chromosomes pair up and then align at the equatorial plane.

3. **Correct Phase Identification**:
- The phase where homologous chromosomes align at the equator is called **Metaphase I** of meiosis. This is distinct from mitosis, where sister chromatids align at the equator during Metaphase.

4. **Conclusion**:
- Therefore, the answer to the question is **Metaphase I of Meiosis**.

### Final Answer:
**Metaphase I of Meiosis**
