Quizplus · Accepted Answer

Research has shown that children who are born to poverty-level parents but are adopted into middle-class families typically have IQ scores that are 10 to 15 points higher than those of their birth mothers. This suggests that environmental factors, such as access to resources and educational opportunities, can have a significant impact on IQ. IQ scores of adopted children show minimal correlation with those of their adoptive parents, indicating that genetics plays a relatively minor role in determining intelligence.
