Answer:
Heritability is important for natural and artificial selection because a trait must be heritable for them to take place. ... Variations that exist in every population are the basis for natural selection. The differences in organisms come from different genetic material.
Explanation:
An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.
A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.
A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:
Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
a) Replacement of a polar amino acid with a nonpolar amino acid at the protein's outer surface
b) Replacement of a polar amino acid with another polar amino acid at the protein's surface
c) Replacement of a polar amino acid with another polar amino acid in the protein's interior
d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior
The predators will feed on the prey lowering their birthrates, but while feeding on the prey, the predators' growth rate will lower since there is less prey to feed on.
