Answer:

Gametic isolation.

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.

I actually do not know this....does someone else?
Lerok [7]
Well, ask yourself, "Do I try hard enough?" "Was it the best I could do?" And well if the answer is yes, then you have nothing to stress out about too much. Maybe talk to your teacher and ask for extra credit. Get tutoring. Talk to a guidance counselor. If none of that helps, well then you're just not the best at the subject, but just try your best. In the future, you won't even remember about all those grades! Coming from a 6th grader, the beginning of the year was super hard. I'm not the best at math, but I'm very good at Language Arts. Everyone has their own weaknesses and strengths. Don't worry about it.
