Behavioural genetics

Behavioural genetics is the field of biology that studies the role of genetics in animal (including human) behaviour. Often associated with idea of "Nature versus nurture", behavioural genetics is highly interdisciplinary, involving contributions from genetics, ethology, psychology, and statistics.

Classically, behavioural geneticists have studied the inheritance of behavioural traits, often using the twin study or adoption study as a tool in humans, or breeding in animal genetics. While animal breeding involves genetics, and much of the material covered in behavior gentics has been realised as needing, at least in part, genetic explanations since the founding of Evolution as a field, Behavior Genetics per-sé is generally considered to have been established with the publication in 1960 of Fuller and Thompson's text Behavior Genetics (Wiley, New York). Scientists in this field include John DeFries, Lindon Eaves, David Fulker, John Loehlin, Nick Martin, Gerald McClearn, Robert Plomin, and Theodore Reich. Relevant journals include Genes, Brain and Behavior, Twin Research and Human Genetics, and Behavior Genetics. Cognate journals include outlets such as Molecular Psychiatry in psychiatric genetics.
