Answer:

Gametic isolation.

Step-by-step explanation:

  • To prevent the mating between the individuals that belong to different species there are two types of barriers that exist in nature - pre-zygotic and post-zygotic.
  • The prezygotic barriers are the ones which prevents the mating to occur and gametic isolation is one of the types of such kind of a barrier.
  • In gametic isolation, the gametes from different species are unable to fertilize each other even if they meet.
  • The gametic isolation is possible because of the incompatibility of the gametes belonging to different species.
  • Therefore, in the given question, since red maple and sugar maple are different species, their sperm and egg are unable to form a zygote and thus, this is an example of gametic isolation.
