Answer:
Natural selection has been studied since Charles Darwing first started his research.
Explanation:
<em>Basically natural selection changes the frequency of traits. Left themselves in large , freely interbreeding populations, the frequency of traits will remain the same from generation to generation. The traits are often heritable, in living organisms, many characteristics are inherited, or passed from parent to offspring. </em>
<em>The reasons why we mightt not see a response to directional selection on such a trait are:</em>
- <em>More offspring are produced than can survive.</em>
- <em> Organisms are capable of producing more offspring than their environments can support. </em>
- <em>Offspring vary in their heritable traits. </em>
When more than one gene controls a trait it is called "<span>define polygenic inheritance".

Answer is 256.
In 1992 the trout population was 4. Thus, initial population of trout is 4. In 1993 it grew to (4)², that is 4×4 = 16, in 1994 it grew (4)³, that is 4×4×4 = 64. This shows the trout has grown exponentially. Therefore, the trout population will be (4)⁴, that is 4×4×4×4 = 256.
