Do parents of children believe in nature as opposed to nurture?

It has been argued that parental status affects one's belief in nature vs nurture with parents more likely to believe in biological (nature) based influences on their children s behavior specifically a belief in differences. Those without children are hard pressed to argue against nature and differences because they are not privy to the same sources of information as parents are (their children!) Do those with children agree that there are biologically based differences in their children? What about those without children? what do you think? nature vs nurture. Is there such a thing as differences?
