Examining the effects of dopamine genes on verbal IQ within and between families.

Journal of neural transmission (Vienna, Austria : 1996) - 1 Mar 2013

Schwartz Joseph A, Beaver Kevin M

Abstract excerpt

Although research findings have revealed that both genetic and environmental factors contribute to variation in IQ at the individual level, no studies have examined how genetic differences contribute to differences in IQ within and between families. The current study uses data drawn from the National Longitudinal Study of Adolescent Health (Add Health) to examine the potential role genetic factors play in shaping...
