What will be an ideal response?
Answer: A good answer will include the following key points.

? It is unlikely that a single gene is involved.
? It is likely that a genetic predisposition interacts with stressful events to create the disorder.
? The relative influence of genetic and environmental factors varies over the life span.
? Years of research have failed to support the notion that depression results from a simple neurotransmitter deficiency.
