Name the stages during which following events occur:
(i) Desynapsis
(ii) Tetrad formation.
(iii) Reduction of amount of DNA per chromosome in meiosis.

Explanation

To answer the question regarding the stages during which specific events occur in meiosis, we can break it down as follows:

### Step-by-Step Solution:

1. **Desynapsis**:
- **Definition**: Desynapsis refers to the failure of synapsis, which is the pairing of homologous chromosomes. When homologous chromosomes do not pair properly, this condition is termed desynapsis.
- **Stage**: Desynapsis occurs during the **Diplotene stage** of meiosis.
