The statement that accurately describes a multifactorial disease is: “Research shows that those who have a parent or sibling with Alzheimer’s are more likely to develop the disease than those who do not have a first-degree relative with Alzheimer’s.”
Explanation: Multifactorial diseases are influenced by multiple genetic and environmental factors. Alzheimer’s disease has a genetic component, as having a family history increases the risk, but other factors, such as lifestyle and environment, also play a significant role in its development. The other options—tuberculosis, traumatic amputations, and sickle cell anemia—describe infectious, traumatic, or single-gene disorders, respectively, and are not classified as multifactorial diseases.
