Answer to Question 1

Answer: A genotype-environment interaction occurs when a genotype responds differently to a given environment. A genotype-environment correlation occurs when a genotype is exposed differently to an environment. An example of the former from the book is the study of Russian juvenile delinquents, the majority of which had experienced maternal rejection; only those with a particular genotype experienced clinical depression as a result of this environmental event. That group carried a gene that is fragile to exposure to the excess dopamine that is often the result of rejection. An example of genotype-environment correlation is one in which a group of infants seek out verbal interaction with caregivers as a result of their genes. Here they are not passive, but are genetically encouraged to behave in a particular way.
