The chromosomes can be divided based on the position of the centromere. A certain chromosomes appears 'L' shaped during the anaphase stage and has centromere slightly away from the middle of the chromosome. Such a chromosome will be

Options

A. Metacentric
B. Sub - metacentric
C. Acrocentric
D. Telocentric

Answer

To solve the question regarding the classification of chromosomes based on the position of the centromere, we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Chromosomes**: Chromosomes can be classified based on the position of the centromere into four main types: metacentric, submetacentric, acrocentric, and telocentric.

2. **Identify the Characteristics of Each Type**:
- **Metacentric**: Centromere is located in the middle, resulting in two equal arms. During anaphase, they appear V-shaped.
- **Submetacentric**: Centromere is slightly off-center, leading to one arm being longer than the other. During anaphase, they appear L-shaped.
- **Acrocentric**: Centromere is located closer to one end, resulting in one very short arm and one long arm. During anaphase, they appear J-shaped.
- **Telocentric**: Centromere is located at the terminal end, resulting in one long arm and no short arm. During anaphase, they appear I-shaped.

3. **Analyze the Given Information**: The question states that the chromosome appears 'L' shaped during anaphase and has the centromere slightly away from the middle.

4. **Match the Characteristics**:
- The L-shaped appearance during anaphase corresponds to the **submetacentric** type of chromosome, as it has a centromere that is slightly away from the middle, resulting in one longer arm and one shorter arm.

5. **Conclusion**: Based on the analysis, the chromosome described in the question is classified as **submetacentric**.

### Final Answer:
The chromosome will be **submetacentric**.
