Find the correct match :
`{:(2 N - 1-1, " i) Trisomy"),(2N +1," ii)Monosomy"),(2 N + 1+1," iii) Nullisomy"),(2N - 2," iv) Double trisomy"),(," v) Double monosomy"):}`

Options

A. a - (v), b-(i), e-(iv), d-(iii)
B. a-(v), b-(i), e-(iv), d-(ii)
C. a-(ii), b-(i), e-(iv), d-(iii)
D. a-(ii), b-(i), e-(iv), d-(v)

Answer

To solve the question of matching chromosomal disorders with their corresponding representations, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Trisomy**: This condition occurs when there is an extra chromosome. For example, if the normal diploid number is 2N, then trisomy would be represented as 2N + 1.
- **Monosomy**: This condition occurs when one chromosome is missing from a pair. It can be represented as 2N - 1.
- **Nullisomy**: This condition occurs when both chromosomes of a homologous pair are missing. It can be represented as 2N - 2.
- **Double Trisomy**: This condition occurs when there are two extra chromosomes, but from different pairs. It can be represented as 2N + 2.
- **Double Monosomy**: This condition occurs when one chromosome is missing from two different pairs. It can be represented as 2N - 2.

2. **Match the Representations**:
- For **Trisomy**: The correct representation is **(2N + 1)**.
- For **Monosomy**: The correct representation is **(2N - 1)**.
- For **Nullisomy**: The correct representation is **(2N - 2)**.
- For **Double Trisomy**: The correct representation is **(2N + 2)**.
- For **Double Monosomy**: The correct representation is **(2N - 2)**.

3. **Identify the Correct Matches**:
- i) Trisomy → **(2N + 1)**
- ii) Monosomy → **(2N - 1)**
- iii) Nullisomy → **(2N - 2)**
- iv) Double Trisomy → **(2N + 2)**
- v) Double Monosomy → **(2N - 2)**

4. **Final Matching**:
- i) **Trisomy** → (2N + 1)
- ii) **Monosomy** → (2N - 1)
- iii) **Nullisomy** → (2N - 2)
- iv) **Double Trisomy** → (2N + 2)
- v) **Double Monosomy** → (2N - 2)

### Conclusion:
The correct matches are:
- i) Trisomy → (2N + 1)
- ii) Monosomy → (2N - 1)
- iii) Nullisomy → (2N - 2)
- iv) Double Trisomy → (2N + 2)
- v) Double Monosomy → (2N - 2)
