Detailed explanation-1: -Artificial selection or selective breeding describes the human selection of breeding pairs to produce favorable offspring. This applies to all organisms – from virus to four-footer, and from pet to food source. Artificial selection aims to increase the productive or esthetic value of an organism to our advantage.

Detailed explanation-2: -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.

Detailed explanation-3: -Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.
