Final answer:
Artificial barriers, such as prezygotic and postzygotic barriers, prevent migration of species and promote interbreeding.
Step-by-step explanation:
Artificial barriers, such as prezygotic and postzygotic barriers, lead to preventing migration of species and promoting interbreeding. These barriers act as obstacles that keep species from moving freely and mixing with other species. For example, prezygotic barriers prevent the fertilization of gametes between two species, while postzygotic barriers prevent the development of viable offspring from interbreeding.
