b. Adults who shared certain physiological characteristics also hold common political beliefs.
c. When asked about attitudes for which there seems to be a genetic predisposition, research participants arequicker to respond to questions and less likely to alter their views toward social norms.
d. The human genome project has identified specific genes that are responsible for the ability to hold positive ornegative attitudes.
