Question
Artificial selection is also known as________.
- Natural selection
- Selective hearing
- Genetic manipulation
- Selective breeding
Hint:
The term artificial selection was given by scientist Charles Darwin. This is not a natural process.
The correct answer is: Selective breeding
Unlike natural selection artificial selection does not allow the organisms to evolve.
- Artificial selection is a process in which humans identify some desirable traits in organisms and through selective breeding, these traits are accumulated in the next generations of organisms.
- Natural selection is caused by random mating while artificial selection is caused by selective breeding.
- Human started the domestication of organisms that are beneficial to them many years ago. Some traits are useful for humans while some are not.
- So, the process of artificial selection allows human to grow plants with desirable traits and to keep the domestic animals with desired traits.
