Quizplus · Accepted Answer

Identical twins share nearly identical DNA, leading to a high likelihood of sharing many traits and characteristics, including IQ score. While parenting styles may have an impact, the genetic influence on intelligence is significant. Choices A, B, and D are more influenced by environmental factors such as parenting style and life experiences, and thus would be less likely to be shared by twins separated at birth.
