Question

Quizplus · Accepted Answer

Identical twins have the same genetic makeup, which could influence their IQ scores. If they were raised in different environments, their scores might differ to some extent, but since they mistakenly think they are fraternal, they might have been treated differently by their caregivers, leading to some environmental differences. Therefore, they will probably resemble each other the most with regard to their IQ scores. A is not the correct answer because fraternal twins share approximately 50% of their genes, which is similar to the genetic similarity between any two siblings. B is not the correct answer because fraternal twins who believed they were identical might have been treated more similarly by their caregivers, leading to environmental similarity that could affect their IQ scores. D is not the correct answer because the genetic and environmental factors that could affect twins' IQ scores are not the same in all pairs.
