The use of specific terminology such as "behavioral psychologist," "selectively breeding," "maze-bright colony," "maze-dull colony," and references to "genes passed from parent to offspring" indicates that the primary audience is biology students. These terms reflect a level of complexity and an understanding of genetics and behavior that would be familiar to students studying biology or related fields, suggesting that the excerpt is tailored for an audience with a background in the subject.
Review the science textbook excerpt and then answer the question.
Genes and Behavior
In the 1940s, behavioral psychologist Robert Tryon conducted an experiment in which rats were placed in a complex maze that had a food reward at one exit. Rats that made fewer errors navigating the maze were bred together to create a "maze-bright colony." Rats that made more errors were bred together to create a "maze-dull colony." After selectively breeding the mice for seven generations, Tryon tested offspring from each colony to determine how quickly those rats would learn the maze. Offspring of the maze-bright rats consistently made fewer errors than the maze-dull offspring. Tyron's research therefore suggests that the ability to navigate the maze successfully was influenced by genes passed from parent to offspring.
