Quizplus · Accepted Answer

Intelligence is determined by both heredity and environment. Research has shown that both genetic and environmental factors contribute to intelligence, and it cannot be determined that one has a greater impact than the other. While genetics may set a certain range of potential for intelligence, environmental factors such as education, nutrition, and experience play a significant role in determining how much of that potential is actually realized. Therefore, it is best to say that both heredity and environment determine intelligence.
