How Do Environmental Factors Interact with Genetic Mechanisms?
Environmental factors can significantly influence the expression of genetic traits, a concept known as gene-environment interaction. For instance, exposure to tobacco smoke can exacerbate the risk of lung cancer in individuals with certain genetic predispositions. Similarly, diet and physical activity can influence the risk of obesity and related metabolic disorders, even in those with a genetic susceptibility. Understanding these interactions is crucial for developing public health interventions that are tailored to both genetic and environmental risk factors.
