Definition of Artificial Selection
Artificial selection is the phenomenon in which humans identify those traits in animals as well as in plants which are desirable. After the selection of the traits, some steps are taken to enhance those selected traits in future generations. It works with exactly the same principle as natural selection.
The only difference is that in natural selection, nature chooses the best traits of an organism whereas, in artificial selections, the traits are chosen by humans. Through the process of selection, the undesirable traits are filtered out of the population gradually. Only those organisms which are best for the environment only survive, grow, and reproduce.
