Question

what is the result when mutations create different alleles in a persons genome?
the variations are harmless.
the variations alter the function of the protein.
the variations create nonfunctional proteins.
the variations either alter the function of the proteins or create nonfunctional proteins.
although the variation could be harmless, it could potentially alter protein function or create nonfunctional proteins.

Explanation:

Mutations can have different outcomes. Some mutations may be silent (harmless), while others can change the amino - acid sequence of a protein. This change can either alter the protein's function (e.g., in sickle - cell anemia, the hemoglobin protein's function is altered) or make the protein non - functional (e.g., some mutations in enzymes can lead to non - functional enzymes). So, mutations that create different alleles can have a range of effects including being harmless, altering protein function, or creating non - functional proteins.

Answer:

Although the variation could be harmless, it could potentially alter protein function or create nonfunctional proteins.
