Which of the following statements is accurate regarding antagonistic pleiotropy?
A) The net fitness effect of an allele experiencing antagonistic pleiotropy may depend on the environment.
B) Alleles experiencing antagonistic pleiotropy should always be strongly selected against.
C) Antagonistic pleiotropy results when a trait is influenced by more than one gene.
D) none of the above
Antagonistic Pleiotropy
The condition that occurs when a mutation with beneficial effects for one trait also causes detrimental effects on other traits.
Net Fitness Effect
The overall impact of an allele or trait on an organism's reproductive success and survival across its lifespan.
Allele
One of any number of alternative forms of the DNA sequence of the same locus.

Final Answer :
A
Explanation :
Antagonistic pleiotropy occurs when a single gene has multiple effects, some beneficial and some detrimental, on an organism's fitness. The net fitness effect of such an allele can indeed depend on the environment, as different environments may alter the balance between the beneficial and detrimental effects.
