Quizplus · Accepted Answer

Studying both identical and fraternal twins who were separated early in life and raised in different environments allows researchers to disentangle the effects of genetics and environment on personality traits. Identical twins share 100% of their genes, while fraternal twins share about 50%, on average. Comparing the similarities between these groups in different environments helps in understanding the heritability of traits.
