occur because a child's characteristics elicit certain types of environments
Active genotype-environment correlations
occurs when children seek out environments that they find compatible and stimulating
development is the result of an ongoing, bidirectional interchange between heredity and the environment
prenatal development that takes place in the first 2 weeks after conception, the creation of the zygote, continued cell division, and the attachment of the zygote to the uterine wall
