Is temperament genetic or environmental?

Is temperament genetic or environmental? Temperament remains fairly consistent, particularly throughout adulthood. Similar temperaments within a family may be attributable to shared genetics and to the environment in which an individual is raised.

Is temperament influenced by nature or nurture? Temperament is a person’s personality, makeup, or disposition that is uniquely his own yet strongly influenced by heredity. It is the interaction of nature AND nurture that produces the person one becomes. Environments affect a baby so profoundly, that in-born temperament can be reshaped over time.
