The reason of fault in gene duplication is

Options

A. Transformation
B. Translocation
C. Mutation
D. None of these

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Gene Duplication**: Gene duplication is a process where a segment of DNA is copied, resulting in two identical segments. This can lead to genetic redundancy and can play a significant role in evolution.

2. **Identifying the Cause of Faults in Gene Duplication**: The question asks about the reason for faults in gene duplication. Faults can arise from various processes, but we need to identify the most relevant one.

3. **Evaluating the Options**:
- **Option A: Transformation**: This process involves the uptake of foreign DNA by a cell, usually seen in bacteria. It is not directly related to gene duplication.
- **Option B: Translocation**: This refers to the movement of genetic material within or between chromosomes. While it can affect gene placement, it is not a direct cause of faults in gene duplication.
- **Option C: Mutation**: This involves changes in the DNA sequence, which can lead to alterations in gene function or structure. Gene duplication itself is a type of chromosomal mutation, and faults can occur during this process.

4. **Conclusion**: The correct answer is **Option C: Mutation**, as faults in gene duplication are often due to mutations that occur during the duplication process.
