In a classic experiment from the 1930s, a biologist conducted selective breeding experiments involving maze-running behavior in rats. he repeatedly bred together males and females that made the fewest mistakes, and he also bred together males and females that made the most mistakes. after eight generations, all mice that descended from "maze-smart" parents were better at running the maze than all mice that descended from "maze-dumb" parents. this study indicates that:
a. maze running is a purely innate behavior in rats.
b. trial-and-error learning in rats appears to have a genetic component.
c. maze running is a purely learned behavior. d. rats move through a maze randomly.
d. nothing can be concluded about maze-running behavior in rats.
