Question

Quizplus · Accepted Answer

Hybridization between populations upon secondary contact can lead to the reinforcement of the two original species through the development of pre- or post-zygotic isolating mechanisms, the creation of one or more new hybrid species, or the formation of a hybrid lineage with higher fitness than either of the parental species. Therefore, all of the above options are possible.
