Detailed explanation-1: -Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.

Detailed explanation-2: -Methods of selection discussed include (1) individual selection (also called mass selection), (2) family selection, (3) sib selection, (4) progeny testing, (5) within-family selection, (6) pedigree selection, and (7) combined selection.

Detailed explanation-3: -Selective breeding versus natural selection Selective breeding is also known as artificial selection. Artificial selection is driven by human intervention.

Detailed explanation-4: -Natural selection is any selection process that occurs as a result of an organism’s ability to adapt to its surroundings. Artificial selection, on the other hand, is selective breeding that is imposed by an external entity, usually humans, in order to enhance the frequency of desirable features.
