Kayla’s family has a history of high blood pressure. High blood pressure can lead to serious health problems such as heart disease. Which statement best explains why Kayla can avoid getting heart disease?

A family history may increase Kayla’s inherited risk, but it does not mean she will definitely develop high blood pressure or heart disease. A phenotype is an observable trait or condition, and it can be influenced by choices and the environment, such as diet, exercise, and medical care. The best answer is that the phenotype of high blood pressure can be changed; her genotype itself cannot simply be changed.
