Answer

To solve the matching question between Column-I and Column-II, we need to analyze each term in Column-I and find the corresponding term in Column-II based on their definitions and characteristics during meiosis.

### Step-by-Step Solution:

1. **Identify the terms in Column-I:**
- A) Pachytene
- B) Zygotene
- C) Diplotene
- D) Leptotene
- E) Diakinesis

2. **Analyze each term:**
- **A) Pachytene:**
- This stage occurs during prophase I of meiosis. It is characterized by the formation of the synaptonemal complex between homologous chromosomes, allowing for genetic exchange (crossing over).
- **Match:** A → (iv) Gene exchange

- **B) Zygotene:**
- This stage is marked by the pairing of homologous chromosomes, which is facilitated by the formation of synapses.
- **Match:** B → (v) Synapsis

- **C) Diplotene:**
- In this stage, homologous chromosomes begin to separate but remain connected at points called chiasmata, where crossing over has occurred. Chiasmata become visible during this phase.
- **Match:** C → (ii) Chiasma visible

- **D) Leptotene:**
- This is the initial stage of prophase I where chromosomes start to condense and become visible. The chromosomes are not yet paired, but the process of synapsis begins.
- **Match:** D → (i) Synizesis

- **E) Diakinesis:**
- This is the final stage of prophase I where the chromosomes condense further, and the chiasmata move towards the ends of the chromosomes, a process known as terminalization.
- **Match:** E → (iii) Terminalisation

3. **Final Matching:**
- A) Pachytene → (iv) Gene exchange
- B) Zygotene → (v) Synapsis
- C) Diplotene → (ii) Chiasma visible
- D) Leptotene → (i) Synizesis
- E) Diakinesis → (iii) Terminalisation

### Correct Answer:
- A → (iv), B → (v), C → (ii), D → (i), E → (iii)
