If a gene is defective or missing, it can potentially cause a disease. Genes are responsible for producing proteins that are crucial for the proper functioning of our bodies. If a gene is defective or missing, it can lead to the production of a protein that does not function properly or is not produced at all. This can disrupt normal bodily processes and lead to various genetic disorders and diseases.

Changing eye color, improving memory, or enhancing physical abilities are not typically direct consequences of a single gene being defective or missing. These traits are usually influenced by a combination of multiple genes and environmental factors. However, certain genetic mutations can potentially influence these traits. For example, specific genetic mutations can lead to variations in eye color.
