Comparison of Epigenetics and Range of Reaction
The epigenetic perspective offers a very different view of gene-environment interactions compared to the range of reaction. In the range of reaction model, a person's genotype is viewed as establishing fixed, limited boundaries for potential development. In contrast, epigenetics asserts that the genotype is not rigidly fixed and limited; instead, environmental factors can flexibly alter how the same genetic information is expressed into different phenotypes over time.

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?

Example of Epigenetics in Identical Twins
Two genetically identical mice are raised in different environments. Mouse A is raised in a standard, quiet cage. Mouse B is raised in an 'enriched' environment with toys, social interaction, and regular exercise. As adults, Mouse B shows significantly lower levels of anxiety-related behaviors and better memory performance than Mouse A, despite having the exact same DNA sequence. Which of the following principles best explains this difference in outcomes?
