Two species regularly come into contact and form hybrids that have higher fitness than either of the parental species.What are some likely consequences of regular hybridization between these species? Check all that apply.
A)evolution of a third species
B)reinforcement of prezygotic isolating mechanisms
C)extinction of one or both of the parental species.
D)increased gene flow between the parental species
E)complete reproductive isolation of the two original species

Question

Quizplus · Accepted Answer

The formation of hybrids with higher fitness can lead to the evolution of a third species (A), potentially cause the extinction of one or both parental species due to competitive disadvantage (C), and increase gene flow between the parental species as hybrids backcross with them (D).
