Question

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. tyrons research therefore suggests that the ability to navigate the maze successfully was influenced by genes passed from parent to offspring. which best indicates that the primary audience is biology students? the writer specifically mentions that genes influenced the mices ability to navigate the maze. the writer uses straightforward language to explain an experiment about gene selection. the writer includes information that only experts would understand. the writer emphasizes the importance of robert tryons work.

Explanation:

Biology students are likely to study gene - related topics. The straightforward explanation of a gene - selection experiment in a science textbook is accessible to students learning biology, as it presents basic scientific concepts without overly complex jargon.

Answer:

The writer uses straightforward language to explain an experiment about gene selection.
