A process in the breeding of organisms by which the scientist chooses to only those forms having certain desirable characteristics is called artificial selection.
- Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. In natural selection, the difference in reproductive success based on a particular trait is driven by natural processes like predators, weather conditions, and environmental constraints.
- Artificial selection is imposed by humans on other organisms. It affects the process of natural selection through change in environmental conditions.
