`{:("Chromosomes", "Position of centromere"),(A."Metacentric",1."At the tip"),(B."Submetacentric",2."Almost near the tip"),(C."Acrocentric",3."At the middle"),(D."Telocentric",4."Slightly away from the middle"):}`

Options

A. A-a, B-b, C-c, D-d
B. A-c, B-d, C-a, D-b
C. A-d, B-c, C-b, D-a
D. A-b, B-a, C-d, D-c

Answer

To identify the correct match between types of chromosomes and their descriptions, we will analyze each type of chromosome and its corresponding position of the centromere.

### Step-by-Step Solution:

1. **Understand Chromosome Types**:
- **Metacentric Chromosome**: The centromere is located at the center of the chromosome, resulting in two arms of equal length.
- **Submetacentric Chromosome**: The centromere is slightly off-center, creating one arm that is longer than the other.
- **Acrocentric Chromosome**: The centromere is located near one end of the chromosome, resulting in one very short arm and one long arm.
- **Telocentric Chromosome**: The centromere is located at the very end of the chromosome, resulting in one arm.

2. **Match Each Type with Its Description**:
- **Metacentric (A)**: Centromere at the middle (3).
- **Submetacentric (B)**: Centromere slightly away from the middle (4).
- **Acrocentric (C)**: Centromere almost near the tip (2).
- **Telocentric (D)**: Centromere at the tip (1).

3. **Final Matching**:
- A (Metacentric) - 3 (At the middle)
- B (Submetacentric) - 4 (Slightly away from the middle)
- C (Acrocentric) - 2 (Almost near the tip)
- D (Telocentric) - 1 (At the tip)

### Summary of Matches:
- **Metacentric**: At the middle (3)
- **Submetacentric**: Slightly away from the middle (4)
- **Acrocentric**: Almost near the tip (2)
- **Telocentric**: At the tip (1)
