Question

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

Answer 1

hybridization is categorized as crossing organisms that have different traits to bring together the best of each. However, this can come with some post-zygotic barriers.

Reduced hybrid viability: hybrid offspring does not survive

Reduced hybrid fertility: hybrid offspring cannot reproduce

hybrid breakdown: first generation of hybrids are viable and fertile, however, their offspring (generation 3) are sterile.
