In Drosophila gene for white eye mutation is also responsible for depigmentation of body parts. Thus a gene that controls several phenotypes is called

Options

A. Oncogene
B. Epistatic gene
C. Hypostatic gene
D. Pleiotropic gene

Answer

To solve the question regarding the Drosophila gene for white eye mutation and its role in depigmentation of body parts, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question refers to a specific gene in Drosophila (fruit fly) that causes a white eye mutation and also affects body pigmentation.

2. **Identify the Phenomena**: The gene in question is responsible for more than one phenotype - the white eye color and the depigmentation of body parts.

3. **Define the Concept**: When a single gene influences multiple phenotypic traits, this phenomenon is known as pleiotropy.

4. **Select the Correct Term**: Based on the definition, the gene that controls several phenotypes (like eye color and body pigmentation) is termed a "pleiotropic gene".

5. **Choose the Correct Answer**: Among the options provided, the correct term for a gene that controls multiple traits is "pleiotropy".

### Final Answer:
The gene that controls several phenotypes is called **pleiotropic gene**.
