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.
Manic depression, or bipolar disease, is another serious mental disorder that has both mania (excessively high moods) and depression (very low, helpless moods). The genetic component is similar to schizophrenia, in that it can run in families and that a person may inherit a `tendency` to develop the disorder.
