Critique of the Range of Reaction Theory

Comparison of Epigenetics and Range of Reaction

Example of Environmental Stimulation on Average Intellectual Potential

Two identical twins are separated at birth. Twin A is raised in an intellectually enriched environment with access to many books, educational toys, and stimulating conversations. Twin B is raised in an environment with limited access to these resources. As adults, both twins show high intelligence, but Twin A scores significantly higher on IQ tests than Twin B. Which of the following statements best explains this outcome according to the idea that one's genetic makeup establishes a potential range for a trait, which is then shaped by external factors?

Two identical twins, who share the exact same genetic makeup, are separated at birth and raised in dramatically different environments. Twin A is raised in a deprived environment with poor nutrition and limited educational opportunities. Twin B is raised in an enriched, stimulating environment with excellent nutrition and high-quality schooling. According to the theory that genes establish a potential range for a trait and the environment determines where the trait falls within that range, what is the most probable outcome regarding their intellectual abilities as adults?
