Advantages And Disadvantages

It may cause mutations, Artificial selection is the process of unintentional modification of a species through human actions which encourage the breeding of certain traits over others. Some disadvantages of artificial selection is that it is inhumane, can cause mutations or produce new problems. An example of the inhumane process is the new way of breeding chickens. These chickens are produced without feathers. Critics say the feather-free chickens will suffer more than normal birds. Males might be unable to mate, because they cannot flap their wings, and naked chickens of both sexes are more susceptible to parasites, mosquito attacks and sunburn.
