Question

read 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.
who is the primary audience?
genetics researchers
people who own pet rats
biology students
professional psychologists

Explanation:

The text is from a science textbook, which is typically used in educational settings. It explains a scientific experiment in a straightforward manner, suitable for students learning about genetics and behavior. Biology students would study such concepts in their curriculum. Genetics researchers and professional psychologists might find it basic, and people who own pet rats are not the main focus as it's an academic - level explanation.

Answer:

biology students
