Those are viable traits to be coded by DNA, to some extent. Some hormones like Serotonine and Dopamine have a direct correlation to the degree of "happiness" or "Sadness" that a person feels.
If both their expression are naturally high, the person would be more predisposed to be happy and to feel well in the world. In the loop-side, if both their expression is naturally low, the person has more disposition to feel depressed.
Both the synthesis and the expression of those hormones is controlled by the major hormone-control region of the human body, the hypophysis, which is connected to the hyphotalamus as well. Both these centers work in tandem in response to metabolical rhythms and sensorial inputs from the environment.
So while those traits can be somewhat regarded to DNA expression, the environment plays the larger role in controlling the levels of those hormones. Thus a person will be more or less "happy" in regards to their personal experience.

Good stuff.
Must be nice to be a biologist. You can say that you have a good reason to be angry, bombard everyone with big words, and they'll just leave you alone.
