Quizplus · Accepted Answer

The fact that depression is more likely to be shared between identical twins, who share 100% of their genetic material, than between fraternal twins, who share only 50% of their genetic material, supports explanations of depression from a biological perspective. This suggests that genetics play a significant role in the development of this disorder. Conditioning, social-cognitive, and psychoanalytic perspectives do not focus primarily on genetic factors.
