Question

Quizplus · Accepted Answer

The statement is incorrect. While genetics plays a role in determining intelligence, environmental factors can also affect phenotypic expression. Therefore, individuals with the same genotype for intelligence may exhibit different phenotypes due to environmental influences, such as education or nutrition. This concept is known as the norm of reaction, not reaction range.

The Same Genotype for Intelligence Leads to the Same Phenotypes
