Detailed explanation-1: -Artificial Selection is a form of selection in which we actively choose the desirable traits that are passed on to the offsprings. Humans have used selective breeding long before Darwin’s Postulates and the discovery of genetics.

Detailed explanation-2: -Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.

Detailed explanation-3: -Artificial selection has influenced the increased yield, nutritional value and growth of individual plants, thus providing food for a growing human population.

Detailed explanation-4: -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-5: -Artificial selection has both positive and negative effects. Positive effects include greater improvements in plants and animals to allow our population to survive. Negative effects include increased risk of genetic diseases. Artificial selection is different from natural selection.
