Answer

To solve the question "A fruit fly exhibiting both male and female traits is?", we can follow these steps:

### Step 1: Understand the Question
The question asks for the term that describes a fruit fly that displays both male and female characteristics.

### Step 2: Analyze the Options
We have four options to consider:
1. Heterozygous
2. Gynandromorph
3. Hemizygous
4. Gynander

### Step 3: Define Each Term
- **Heterozygous**: This term refers to an organism that has two different alleles for a particular gene. It does not imply the presence of both male and female traits.
- **Gynandromorph**: This is a specific term used to describe an organism that has both male and female characteristics. This condition is often observed in insects, including fruit flies.
- **Hemizygous**: This term refers to an organism that has only one allele for a gene, typically seen in males for genes located on the X chromosome. It does not relate to the presence of both male and female traits.
- **Gynander**: This term is similar to gynandromorph but typically refers to individuals that have diploid female characteristics and haploid male characteristics. It is not the correct term for a fruit fly exhibiting both traits.

### Step 4: Identify the Correct Answer
Given the definitions, the term that best describes a fruit fly exhibiting both male and female traits is **gynandromorph**. Therefore, the correct answer is option 2: **gynandromorph**.

### Step 5: Conclusion
The fruit fly exhibiting both male and female traits is called a **gynandromorph**.
