Final answer:
Genetic risk factors can influence the likelihood of developing certain diseases, but they do not guarantee disease development.
Step-by-step explanation:
Genetic risk factors can influence the likelihood that a person will later develop certain diseases. These risk factors are associated with an increased susceptibility to the associated diseases, but they do not guarantee that the person will develop the diseases. For example, certain mutations in the BRCA1 and BRCA2 genes are linked to a higher risk of breast and ovarian cancer in women, but not every woman with these mutations will develop cancer.
