Assertion : When yellow bodied, white-eyed Drosophila females were hybridised with brown bodied, red-eyed males, the two genes segregate independently of each other.
Reason: The two genes are on the different chromosomes and the proportion of non-parental gene combination is much higher than the parental type.

Options

A. Assertion and reason both are correct statements and reason is the correct explanation of the assertion.
B. Assertion and reason both are correct statements, but reason is not the correct explanation of the assertion
C. Assertion is true, but reason is false statement.
D. Assertion is false, but reason is true statement.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that when yellow-bodied, white-eyed Drosophila females are hybridized with brown-bodied, red-eyed males, the two genes segregate independently of each other.
- This implies that the traits (body color and eye color) are inherited separately.

2. **Understanding the Reason**:
- The reason given is that the two genes are on different chromosomes, and the proportion of non-parental gene combinations is much higher than the parental type.
- This suggests that because the genes are located on different chromosomes, they assort independently during gamete formation, leading to a higher frequency of recombinant (non-parental) phenotypes.

3. **Analyzing the Relationship**:
- In Drosophila, genes that are located on the same chromosome tend to be linked and do not assort independently.
- If the assertion were true, it would mean that the genes are assorting independently, which is typically the case when they are on different chromosomes.

4. **Evaluating the Truth of Each Statement**:
- The assertion is **false** because the genes for body color and eye color in Drosophila are likely linked, meaning they do not segregate independently.
- The reason is **true** because if the genes were on different chromosomes, they would assort independently, leading to a higher proportion of non-parental combinations.

5. **Conclusion**:
- Since the assertion is false and the reason is true, the correct answer is that the assertion is false and the reason is true.

### Final Answer:
- Assertion: False
- Reason: True
