Question

Quizplus · Accepted Answer

While having a short copy of the serotonin transporter gene has been linked to an increased vulnerability for MDD, it is not a guarantee that Craig will develop the disorder. Additionally, environmental factors such as growing up in foster care could also contribute to his vulnerability. Research on the interplay between genetics and environment in the development of MDD has shown mixed results, making it uncertain if Craig will develop the disorder.
