Quizplus · Accepted Answer

Research has shown that individuals who have experienced multiple negative life events and possess two copies of the short version of the gene have the highest likelihood of experiencing an episode of major depression. While experiencing multiple negative life events alone or possessing one copy of the short version of the gene can also increase the risk of depression, the combination of both factors results in the greatest probability of depression. Possessing two copies of the long version of the gene may actually provide some protection against depression.
