In which stage, actual reduction of chromosome number occurs in meiosis?

Explanation

To determine the stage in meiosis where the actual reduction of chromosome number occurs, we can follow these steps:

### 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 from one diploid cell. It consists of two main stages: Meiosis I and Meiosis II.

2. **Identifying the Stages**:
- **Meiosis I**: This is the reductional division where homologous chromosomes separate.
