THE GENETICS OF BEHAVIOR • Heritability refers to how much characteristics depend on genetic differences. • Estimates of hereditary influences are often difficult to infer and are prone to error. • Sources of error include the following: – The inability to distinguish between the effects of genes and prenatal influences. – Environmental factors can inactivate genes.

THE GENETICS OF BEHAVIOR • Genes do not directly produce behaviors. • Genes produce proteins that increase the probability that a behavior will develop under certain circumstances. • Genes can also have an indirect affect. – Genes can alter your environment by producing behaviors or traits that alter how people in your environment react to you.
