Suppose a gene mutation does not affect the protein that the gene codes for. What effect will the mutation have on the individual? Explain your reasoning.

No effect.

Explanation:

Let us say that we have a protein with given codon GUU, coding for Valine. However, the mutation codes for GUC, also for Valine. This mutation, therefore, would have no discernible effect on the protein, and therefore not affect the protein's function.
