Question

Which situation is an example of a prezygotic barrier?

a) Two species producing a sterile hybrid
b) Two species having different courtship behaviors
c) Two species producing viable hybrid offspring
d) Two species having similar ecological niches

Answer 1

Courtship behaviors between two species is an example of a prezygotic barrier.

Step-by-step explanation:

A prezygotic barrier is a mechanism that blocks reproduction from taking place before zygote formation. One example of a prezygotic barrier is when two species have different courtship behaviors (option b). This means that the organisms have unique behaviors and signals that they use to attract mates. If the courtship behaviors differ between two species, they will not recognize each other as potential mates and reproduction will not occur.
