Hybridization Between Populations Upon Secondary Contact May Result in ________

Question

Hybridization between populations upon secondary contact may result in ________.
A) reinforcement of the two original species by way of pre- or post-zygotic isolating mechanisms
B) the creation of one or more new species as hybrids between the two parental species
C) the creation of a hybrid lineage that has higher fitness than either of the parental species
D) All of the above are possible.
E) None of the above are possible.

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.
