Two populations of birds with somewhat different coloration live on opposite sides of a peninsula. The habitatbetween the populations is not suitable for these birds. When birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. These offspring will breed with eachother or with birds from either parent population, and all offspring of these pairings appear intermediate to variousdegrees. What keeps the two populations separate?

A. temporal reproductive isolation

B. lack of hybrid viability

C. behavioral reproductive isolation

D. spatial reproductive isolation-the only reason these two species don'tmate is because of the inability of the middle land to be occupied

Option D, spatial reproductive isolation-the only reason these two species don't mate is because of the inability of the middle land to be occupied

Explanation:

It is clear from the question that the two bird populations with different color are able to mate and reproduce viable and fertile offspring when brought together. Hence, the only problem due to which these two bird population were not breeding with each other was their distant location and habitat.

Location and habitat are characteristic of spatial distribution and hence they were separate because of spatial reproductive isolation

Hence, option D is correct
