Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of tomato genetics.
Step 2: Detailed Explanation:
The gene for fusarium wilt resistance (I gene) in tomato is located on chromosome 8.
It provides resistance to Fusarium oxysporum f. sp. lycopersici.
Chromosome 3 (A): Not the location.
Chromosome 5 (B): Not the location.
Chromosome 6 (C): Not the location.
Thus, chromosome 8 is the correct answer.
Step 3: Final Answer:
Thus, the gene for fusarium wilt resistance in tomato is located on chromosome 8, which corresponds to option (D).
