Document Summary
Behavioral genetics: which is the study of the genetic and environmental. Nature and nurture as allies contributions to individual differences in personality and behavior. The best characterization of the nature- nurture issue is that nature and nurture transact. That is, genes and environment can work separately, together, or they may influence one another. Certain environments have different effects on people deepening on their specific genetic makeup. We call this combination of nature and nurture a genotype- environment interaction. This is called a genotype- environment correlation. Phenotype = genotype + environment + gene- environment correlation + gene- . Genes and environment as co- actors. Heritability refers to differences across a group or population of people- not to a specific person. It is impossible to say how much of your height is due to your genes. Together, heritability, environmentality, and measurement error account for all the differences we see among people on a given characteristic.
