Definition
Behavior genetic studies strive to differentiate between the variability that is attributable to genes and the variability that is attributable to the environment. This is typically done through a systematic evaluation of the correlation between twins (both monozygotic and dizygotic), non-twin siblings, or between parents and offspring. The term is typically reserved for research done on personality variables and ability scores.
Introduction
Behavior genetics once stood in the foreground of a significant amount of controversy in psychology, particularly with regard to the debate as to the relative importance of “nature” and “nurture.” Years of behavior genetic research have, however, suggested that most personality characteristics are at least partially genetically determined and that most personality traits are between 40 % and 60 % heritable (Johnson et al. 2008). Modern behavior genetic research has begun to involve...
