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.
what is the texts main purpose?
to explain the role of rats in research
to explain the significance of tryons experiment
to argue that genes are solely responsible for navigational abilities
to highlight tryons contributions to science

Explanation:

Breve explicación:

El texto describe el experimento de Tryon con ratas en un laberinto y cómo los resultados sugieren que la habilidad para navegar el laberinto se ve influida por los genes heredados. El enfoque principal es explicar la importancia de este experimento. No se enfoca solo en el papel de las ratas, ni argumenta que los genes son la única causa de las habilidades de navegación, ni destaca en general las contribuciones de Tryon a la ciencia sino específicamente este experimento.
