Abstract
Research that is founded in or incorporates elements from the biosocial perspective holds that both biological and environmental factors work together to influence human behavior. Behavioral genetic modeling evaluates what portion of the variance in a trait or behavior is attributable to genetic and environmental factors. ACE models make use of structural equation modeling to decipher the contributions of genetics, shared environmental factors, and nonshared environmental factors to explain the variance of a measured variable. Behavioral genetic models regularly find that approximately 50% of the variance in antisocial behavior is attributable to additive genetic components. The most common type of length polymorphism examined in candidate gene studies are those that have variable numbers of tandem repeats. Research has found that significant portions of the variation in antisocial behavior, impulsivity, psychopathic traits, and many other central criminological concepts are at least partially heritable.
