Question

Quizplus · Accepted Answer

To untangle the influence of heredity and environment on intelligence, measuring and comparing the IQs of identical twins, fraternal twins, and siblings reared either together or separately can help isolate the effect of genetics from environmental factors. This helps to understand which factors contribute to intelligence. A longitudinal study may not be practical, while calculating the IQ of parents and offspring may not show the influence of the environment accurately. Mapping the genes responsible for intelligence is still a topic under research, and their influence may not provide a complete picture of the environmental factors that affect intelligence. Therefore, C is the best choice for untangling the influence of heredity and environment on intelligence.
