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. tryons research therefore suggests that the ability to navigate the maze successfully was influenced by genes passed from parent to offspring. what is the texts main purpose? to explain the role of rats in research to highlight tryons contributions to science to explain the significance of tryons experiment to argue that genes are solely responsible for navigational abilities

Explanation:

The text details Tryon's experiment with rats in a maze and concludes that his research suggests gene - influence on maze - navigation ability. This indicates the significance of his experiment. It doesn't just focus on rats' role in research or Tryon's contributions in a general sense, and it doesn't claim genes are solely responsible.

Answer:

to explain the significance of Tryon's experiment
