Many amphibian species release their sperm and eggs directly into a watery environment.All of the following mechanisms might ensure species-specific fertilization in these populations except _____.
A)acrosomal complexes in sperm
B)complex coverings of the egg
C)specific protein binding between sperm and egg
D)fertilization envelopes
E)blocking of non-species-specific mRNA sequences

Question

Quizplus · Accepted Answer

Blocking of non-species-specific mRNA sequences is not a mechanism used for species-specific fertilization in amphibians. The other options, including acrosomal complexes in sperm, complex coverings of the egg, specific protein binding between sperm and egg, and fertilization envelopes, are all mechanisms that help ensure species-specific fertilization in amphibians.
