Analyze the nature of genetic mutations

Mutations are changes in the DNA sequence of an organism. These changes can alter proteins, leading to different phenotypic effects.

Evaluate the potential effects of mutations

• Harmful (A): Many mutations disrupt normal gene function, causing genetic disorders or reducing survival rates.
• Helpful (B): Some mutations introduce beneficial traits that enhance survival or adaptation, driving evolution.
• Neutral (C): Many mutations occur in non-coding regions or do not alter the resulting amino acid sequence, having no effect.

Determine the correct option

Since mutations can be harmful, helpful, or neutral, all three statements (A, B, and C) are correct.
