Question

The pollen, or sperm, from a red maple tree is unable to fertilize the eggs from a sugar maple tree. this is an example of what type of isolating mechanism?

Answer 1

Gamete isolation
which of the following lists the level of taxonomic classification in order from the most inclusive to the least inclusive
domain- kingdon- phylum- class- order

Answer 2

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.
