Definition
In psychology, interaction refers to the interplay that occurs when the effect of one factor (such as environment) depends on another factor (like heredity).
This is a longstanding discussion regarding the relative importance of an individual's innate qualities ("nature") versus personal experiences ("nurture").
This field studies changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. It’s like dancers changing their routine based on audience reaction.
Gene-Environment Correlation: This term refers to how your genes can influence the environments you are exposed to. Like a dancer who loves hip-hop likely finding themselves in more hip-hop related environments.
