Mutations may or may not affect the phenotype because they can occur in coding or non coding areas of the DNA. If they occur in coding areas of the DNA, the protein that is coded in that part could be processed incompletely or have a different amino-acid in some part of its structure, this would affect the phenotype. If they occur in non coding areas, this would have no effect on the phenotype.
