Answer to Question 2
Passive genotype/environment interaction notes that parents contribute the genes to the child in the first place, and parents also tend to express their genes in the environment they create for the child. Thus, if the parents are extraverts, they would tend to create a highly social, outgoing environment that would model extraversion for the child. The evocative type of genotype/environment interaction occurs when genetic traits displayed by the child elicit behavior from others that in turn enhances those traits. For example, others might respond to an extraverted child by behaving in a highly sociable fashion, thus enhancing and reinforcing extraversion. An active genotype/environment interaction occurs when the child's traits result in the child seeking out niches that support and maintain those traits. Thus, an extraverted child will actively seek situations involving socializing with others, and those situations maintain the extraversion.
