What is artificial selection? Do you think it affects the process of natural selection? How?

Answer :

Artificial selection is a type of selective breeding in which humans select desired traits or a combination of traits for exploiting the variations among species. It can affect natural selection. For example when Mendel selected and crossed only the true breeding varieties which were created by continuous self pollination; the process of natural selection get arrested and promoted the growth of desired traits only in plants. This can prevent the plant from getting better adapted by eliminating harmful and promoting useful genes through natural selection. Artificial selection is fast process, it cannot bring the evolutionary change brought by natural selection in population, and can eventually lead to decreased yield and growth.
