Explanation:
Detailed explanation-1: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Detailed explanation-2: -Because of selective breeding, future generations of selectively bred plants and animals will all share very similar genes which will reduce variation.
Detailed explanation-3: -Yes, artificial selection affects the process of natural selection. Artificial selection depends on selections and improvement of the traits to increase the yield according to human preference. This interferes with the natural selection of traits.
