Which Mechanism Prevents Fish Sperm from Fertilizing Frog Eggs

Question

Which mechanism prevents fish sperm from fertilizing frog eggs?
A) Energetic barriers
B) Biological barriers
C) Prezygotic barriers
D) Ecological barriers
E) Postzygotic barriers

Accepted Answer

Prezygotic barriers prevent different species from mating or ensure that if they do mate, fertilization does not occur. In the case of fish sperm and frog eggs, prezygotic barriers such as differences in reproductive organs, mating behaviors, or timing of reproduction prevent cross-species fertilization.
