Answer #1

Choice B: Reproductive isolation

Explanation: Biological species not only interact with each other, but they also reproduce in order to enhance their progeny size and follow in the future generations. If a group of individuals is isolated from each other on the basis of their behaviour or seasonal requirements but allowed to reproduce, they will definitely share their gene pools and isolation will be violated. However, if reproductive isolation is there among the individuals, there would be no sharing of the gene pool and complete solicitation and isolation is achieved.

The most likely reason for the disappearance of a hybrid zone in parapatric speciation, resulting in completion of the speciation process is A. Hybrid individuals likely have the right combination of traits for high fitness in the intermediate habitat. B. Strong selection outside the hybrid zone on traits that lead to fewer mating events with individuals on the opposite side of the cline. C. Stabilizing selection in the hybrid zone. D. Negative assortative mating across the hybrid zone.
