Genes that change their location on chromosome are

Options

A. split genes
B. Duplicate genes
C. Jumping genes
D. Pleitropic gense

Answer

To solve the question "Genes that change their location on chromosome are," we can follow these steps:

### Step 1: Understand the Options
The options provided are:
- Split genes
- Duplicate genes
- Jumping genes
- Pleiotropic genes

### Step 2: Define Each Term
1. **Split genes**: These are genes that are interrupted by non-coding sequences (introns) but do not change their location on chromosomes.
2. **Duplicate genes**: These are genes that have been copied within the genome but do not move from their original location.
3. **Jumping genes**: Also known as transposons, these are segments of DNA that can move from one location to another within the genome.
4. **Pleiotropic genes**: These are genes that affect multiple traits but do not change their location.

### Step 3: Identify the Correct Answer
From the definitions, we can see that:
- **Jumping genes** (transposons) are the only type of genes that can change their location on chromosomes.

### Step 4: Conclusion
Thus, the correct answer to the question is **jumping genes**.

### Final Answer
**Jumping genes** are the genes that change their location on chromosomes.
