What is a key benefit of understanding the function of genes through genetic mapping?

Understanding the function of genes through genetic mapping provides critical insights that help identify potential targets for gene therapy. By mapping the genes associated with specific diseases or conditions, researchers can pinpoint which genes may be dysfunctional or defective. This information is vital for developing targeted therapies that aim to correct or replace the faulty genes, ultimately providing a therapeutic approach to treat or potentially cure genetic disorders.

While genetic mapping can inform various applications, such as genetic engineering, it does not guarantee a healthy population or completely eradicate diseases. Instead, it serves as a foundational tool to enhance our understanding of genetic contributions to health and disease, allowing for informed approaches to treatment.
