Explanation:

Artificial breeding can be described as a process by which human breed those plants and animals which have qualities of their interest, so that the offsprings produced will result in the desired qualities. For example, in the statement A, a farmer is crossing a tree that produces large apples with a tree that produces sweet apples. As a result of this breeding, the offsprings produced might have qualities from both the parents.
