In health, genetic predisposition occurs when a person is more likely to develop a specific disease or condition due to his/her genes. For example, you are predisposed to have diabetes if your parents, grandparents, and other relatives have develope it. However, predisposition is not the only factor contributing to the development of disease as environmental factors including lifestyle play an important role. This implies it is false a person who is predisposed to be obese cannot improve his or her overall health because through an adequate lifestyle that includes a healthy diet and exercise the person can improve his/her health and avoid obesity.
