Question

Quizplus · Accepted Answer

Intelligence is a multifactorial trait that is influenced by both genetic and environmental factors. It cannot be attributed to a single factor such as head size or lack of environmental influence. The low concordance in MZ twins suggests that genetic factors account for only a portion of intelligence variation, while the remaining variation is due to environmental factors.
