Question
Define Gene environment (G E) interaction. Give an example of a study (either your own or one from the book) that could illustrate the interaction between genes and the environment.
Gene environment (G E) interaction refers to the interaction of a specific measured variation in the DNA and a specific measured aspect of the environment. In a study, adults who experienced parental loss as young children were more likely to have unresolved attachment issues as adults only when they had the short version of the 5-HTTLPR gene. The long version of the serotonin transporter gene apparently provided some protection and ability to cope better with parental loss.
