If formerly interbreeding organisms are prevented from the production of fertile offspring, a. reproductive isolation has occurred.  

Reproductive isolation refers to an accumulation of transformative instruments, practices, and physiological procedures basic for speciation. They keep individuals away from various species from delivering posterity, or guarantee that any posterity is sterile. These obstructions keep up the respectability of an animal group by decreasing quality stream between related species.

The components involved in isolation are hereditarily controlled and can show up in species whose geographic dispersions are dependant or are independent.
