Question

For natural selection to result in evolutionary change variation must exist in a population. reproductive success of different phenotypes must differ. variation must be inherited from one generation to the next. all of the above. Founder effects and bottlenecks are expected only in large populations terms used in bars mechanisms that increase genetic variation in a population forms of genetic drift Stabilizing selection differs from directional selection because in the former, phenotypic variation is reduced but the average phenotype stays the same, whereas in the latter both the variation and the mean phenotype change. the former requires genetic variation, the latter does not. intermediate phenotypes are favored in directional selection.

Explanation / Answer

1) D 2) D 3) A I know that the first two are correct, but I have never heard of the stabilizing selections, but the answer sounds logical. I hope this helps!
