Answer:

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.
