Extent to which variability in a trait is due to genetic factors (in the population) Genetic factors contribute to most disorders, but usually account for less than. Non-shared environment: accounts for difference amongst one another even between twins (identical or fraternal, epigenetics. How the environment can alter gene expressions or function. Specific cultural or social influences can affect which genes turn on: models, diathesis-stress model- the water cup one, gene environment correlation model.

Prominent during critical periods of life like childhood.
