gene by environment correlation(English)

• phenomenon whereby genes influence individual variations in exposure to adverse, and/or protective, environments. Three separate types have been described: passive, evocative/ reactive, and active. In passive rGE, parents pass on genes and also provide an environment, both of which influence the child’s development. For example, depressed parents are likely to pass on depressogenic genes to their children. These correlated genetic and environmental influences increase the risk of depressive symptoms in the child. In evocative rGE, heritable traits influence the reaction of others and hence the environment provided by others. In active rGE, a child’s heritable traits influence his or her choice of environment. For example, a shy child may have reduced motivation to go out and do enjoyable peer activities. This reduced exposure to positive environments may increase depressive symptoms. The presence of significant correlation between genetic and environmental factors can make interpretation of results difficult, because it is difficult to distinguish whether it is the genes, the environment, or both that influence an outcome of interest
