True or False: Individuals with sickle cell trait do have symptoms under normal conditions.

Individuals with sickle cell trait typically do not exhibit any symptoms under normal conditions. Sickle cell trait is a genetic condition where a person inherits one normal hemoglobin gene and one sickle-shaped hemoglobin gene. This means that, while they carry the trait, their blood generally functions normally and does not lead to the symptoms or health issues associated with sickle cell disease.

People with sickle cell trait may have some risk of complications under extreme conditions such as high altitude, intense physical exertion, or significant dehydration, but such scenarios are not reflective of everyday life. Under normal circumstances, they tend to remain asymptomatic and lead typical lives without the debilitating symptoms seen in those with sickle cell disease. This understanding clarifies why the statement regarding the presence of symptoms under regular conditions is false.
