If a part of chromosome gets separted and reattached in reverse positoion to the same chromosome, the mutation is called

Options

A. Inversion
B. Transverion
C. Transloction
D. Gene mutation

Answer

To solve the question, we need to identify the type of mutation that occurs when a part of a chromosome gets separated and reattached in reverse position to the same chromosome. Let's break down the solution step by step:

### Step-by-Step Solution:

1. **Understanding Chromosomal Mutations**:
- Chromosomal mutations involve changes in the structure of chromosomes. These can include deletions, duplications, inversions, and translocations.

2. **Identifying Inversion**:
- Inversion is a specific type of chromosomal mutation where a segment of a chromosome is removed, rotated 180 degrees, and then reattached to the same chromosome. This results in the genes in that segment being in reverse order.

3. **Analyzing the Question**:
- The question states that a part of a chromosome gets separated and reattached in reverse position to the same chromosome. This description matches the definition of inversion.

4. **Evaluating Other Options**:
- **Transversion**: This refers to a point mutation where a purine is replaced by a pyrimidine or vice versa. It does not involve chromosomal segments.
- **Translocation**: This involves the exchange of segments between non-homologous chromosomes, which is not the case here.
- **Gene Mutation**: This is a broader term that includes various types of mutations, but it does not specifically describe the rearrangement of a chromosome segment.

5. **Conclusion**:
- Based on the definitions and the analysis, the correct answer to the question is **inversion**.

### Final Answer:
The mutation is called **inversion**.
