The correct answer is the nature-nurture issue.
The nature-nurture issue refers to a debate in the social sciences about whether biological factors (a person's nature) or enivronmental factors (a person's "nurture") impact an individual's development, behavior and actions. According to proponents of the "nature" argument, our genes have a more significant role than environmental factors when determining our personality. Whereas, those who support the "nurture" argument would state that environmental factors (such as our early childhood upbringing) play a larger role than our genes when determining our personality.
