Which of these characters cannot be transferred from a male parent to a male progeny in Drosophila ?

Options

A.
B.
C.
D.

Answer

To solve the question of which character cannot be transferred from a male parent to a male progeny in Drosophila, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Drosophila Genetics**:
- Drosophila (fruit flies) have a specific sex chromosome system. Males have one X chromosome and one Y chromosome (XY), while females have two X chromosomes (XX).
- This difference in sex chromosomes is crucial for understanding inheritance patterns.

2. **Identify the Characters in Question**:
- The question implies that we are looking at specific traits or characters that may or may not be passed from male to male progeny.
- Common traits in Drosophila include eye color, body color, and wing shape.

3. **Analyze the Inheritance Patterns**:
- Traits that are linked to the X chromosome can be passed from male to female offspring but not from male to male offspring since males inherit their Y chromosome from their father and not the X chromosome.
- Therefore, any trait that is X-linked cannot be passed from a male parent to a male progeny.

4. **Determine the Correct Answer**:
- Based on the understanding that male Drosophila do not pass on their X-linked traits to male progeny, the character that cannot be transferred from a male parent to a male progeny is the one that is X-linked.

5. **Conclusion**:
- The character that cannot be transferred from a male parent to a male progeny in Drosophila is the one that is X-linked.

### Final Answer:
The character that cannot be transferred from a male parent to a male progeny in Drosophila is the one that is X-linked.
