Question

Quizplus · Accepted Answer

Twin studies involve comparing the similarities in intelligence between identical twins who share 100% of their genes, and fraternal twins who share only 50% of their genes. By comparing these two groups, researchers can estimate how much of the variability in intelligence is due to genetic factors, and how much is due to environmental factors. This method has been used extensively in behavioral genetics research to study the heritability of intelligence.
