Question

There are two groups of pine trees that appear to be very similar phenotypically and genotypically. However, one releases pollen in January, when the female structures of that group are receptive, and one in March. What kind of reproductive barrier is this?

Answer 1

Answer:

Temporal isolation

Explanation:

Temporal isolation is a type of prezygotic reproductive barrier that occurs when two populations of a species have different breeding seasons or reproduce at different periods, making it difficult or impossible for interbreeding between both to occur even when they dwell in the same habitat.

The difference in the time when both groups of pine trees release pollen when their female structures are receptive, will make it impossible for both groups to interbreed. This kind of reproductive barrier is referred to as temporal isolation.
