Quizplus · Accepted Answer

Research suggests that both genetic and environmental factors play a role in intelligence, but genetic factors tend to have a stronger influence. Studies on twins and adopted children have shown that genetics can account for up to 50-80% of intelligence differences among individuals. However, environmental factors, such as access to education and nutrition, can also impact intelligence. Therefore, it can be said that genetic factors influence intelligence in a positive manner and environmental factors can also have an impact.
