Document Summary
Studied by haeffel et al. , with boys ordered by court for delinquent detention. Looked for genetic and environment differences between youths who depressed and not. Found no impact of genes/environment on rates of depression. Genotypes: genetic makeup which code for specific traits. Different result obtained when divided samples according to genotypes: youth had both stressful environment and genotype 3: High chance of being in depression ii)youth with any 3 genotypes without maternal rejection/ maternal rejection with genotype1&2. Combination of environment (maternal) and genetics predicted related outcomes. Behavioral genetics: study of genetic and environmental contribution to individuals difference in personality and behavior. Human behaviors is an inextricable combination of both genetics and environment. Nature and nurture transact:- genes and environment can work separately or together or influence one another. May operate separately but in parallel to influence personalities. Environment may have different effects on people depending on their specific genetic makeup. Different small components together can form something fundamentally different.
