Question

Quizplus · Accepted Answer

Behavioral disorders are influenced by a combination of genetic and environmental factors. While some genes may have a major influence on the disorder, others may only have a small input. Additionally, environmental triggers may contribute to the development of the disorder. Therefore, it is unlikely that a single gene causes the disorder in everyone.
