The finding that the attitudes of identical twins are more similar than those of fraternal twins supports the hypothesis that there is a genetic component to some attitudes.

Therefore, if attitudes are more similar among identical twins, it suggests that genes play a role in the development of those attitudes. Option B would not support the genetic hypothesis, as it suggests that fraternal twins are just as similar. Options C and D relate to environmental factors and do not necessarily support the genetic hypothesis.
