Question:
In parasitic castration
In parasitic castration
Show Hint
Parasitic castration redirects host energy from reproduction to parasite growth and survival.
Updated On: Jun 19, 2026
- Gonads of the host degenerate
- Size of the Gonads of the host increases
- No change in the Gonads of the host
- Gonads of the parasite degenerate
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Define parasitic castration.
- Parasitic castration occurs when a parasite infects a host and inhibits the host’s reproductive capacity.
Step 2: Effect on host gonads.
- Parasite consumes nutrients or secretes inhibitory compounds.
- Host gonads degenerate and fail to produce gametes.
Step 3: Effect on parasite.
- Parasite reproduces using host resources.
- Parasite’s reproductive system remains unaffected or develops normally.
Step 4: Comparison with other options.
- Size increase of host gonads: wrong.
- No change: wrong, degeneration occurs.
- Gonads of parasite degenerate: wrong.
Step 5: Conclusion.
- Correct answer: Gonads of the host degenerate.
- Parasitic castration occurs when a parasite infects a host and inhibits the host’s reproductive capacity.
Step 2: Effect on host gonads.
- Parasite consumes nutrients or secretes inhibitory compounds.
- Host gonads degenerate and fail to produce gametes.
Step 3: Effect on parasite.
- Parasite reproduces using host resources.
- Parasite’s reproductive system remains unaffected or develops normally.
Step 4: Comparison with other options.
- Size increase of host gonads: wrong.
- No change: wrong, degeneration occurs.
- Gonads of parasite degenerate: wrong.
Step 5: Conclusion.
- Correct answer: Gonads of the host degenerate.
