Which of the following is NOT a mechanism by which prezygotic barriers prevent fertilization?

  • A: Impeding members of different species from attempting to mate.
  • B: Preventing an attempted mating from being completed successfully.
  • C: Causing hybrid offspring to be infertile.
  • D: Hindering fertilization if mating is completed successfully.

Explanation

Prezygotic barriers prevent fertilization from occurring. These include impeding mating attempts, preventing successful mating completion, or hindering fertilization even if mating is completed. Causing hybrid offspring to be infertile is a postzygotic barrier, acting after the zygote has formed.
