Quizplus · Accepted Answer

A pleiotropic effect refers to a single gene that affects multiple traits or conditions. In the context of mental disorders, this would mean that a single gene is associated with multiple disorders. This is different from polygenic inheritance, which involves multiple genes contributing to a single trait or condition. Additionally, the interaction between genes and the environment can also play a role in the development of mental disorders.
