You're both right. Genetics play a mild role in major depression (a bigger role in bipolar disorder). Genetics may serve as a predisposing factor to depression, but the evidence is growing that depression has a great deal to do with the ongoing and repetitive interactions within the family.

Over time, natural selection weeds deleterious alleles out of a population â when the dominant deleterious alleles are expressed, they lower the carrier's fitness, and fewer copies wind up in the next generation.
