Question 113

Selective breeding and natural selection both change how common an allele is in a population. What is the difference between them?

  1. Only selective breeding changes how common an allele is
  2. Who or what decides which individuals become parentsCorrect answer
  3. Natural selection is the faster of the two because it is natural
  4. Only natural selection can act on characteristics that are inherited

Explanation

In one process a breeder picks the parents with a purpose in mind, and in the other the conditions of the habitat leave some individuals more likely to survive and breed, so the selecting agent is the whole of the difference. Treating the two as one process hides that one of them has a goal and the other has none, and speed is not what separates them.
