Quizplus · Accepted Answer

The evidence from identical twin studies suggests that genes play a significant role in determining intelligence, with high correlations when raised together or apart.

Option D is incorrect as high correlations in intelligence among people living in the same home do not necessarily indicate that intelligence is almost 100 percent environmental.
