Explanation:

Inbreeding occurs when offsprings result from two individuals who have a similar genetic sequence because they are closely related. The offsprings borne are prone to be defective because of the similarity between their parents' genes.  Inbreeding depression also occurs because the offsprings are not physically fit and can easily succumb to death.

The opposite of inbreeding is crossbreeding which prevents the negative traits that are associated with inbreeding.
