The GxE Model

The GxE (Gene-by-Environment) Model explains how our genes and the environment interact to influence traits or behaviors. Essentially, it suggests that genetic predispositions may be expressed differently depending on environmental factors, such as experiences, lifestyle, or surroundings. For example, someone might have a genetic tendency for depression, but whether it manifests can depend on stress levels or support systems. The model emphasizes that both biology and environment are interconnected, shaping outcomes in a complex way rather than operating independently. This helps us understand that both our genes and our experiences contribute to who we are.
