The reaction range theory suggests that genetics sets a range for potential intelligence, but environmental factors such as upbringing and education determine where within that range an individual falls. Vasia's disadvantaged upbringing likely resulted in a lower IQ compared to her genetically identical twin who was raised in an enriched environment.
