When Tryon (1940) bred "maze-bright" rats together, he found that:
A) there was no improvement in maze learning across generations.
B) the first generation made fewer errors, but subsequent generations showed no improvement in maze learning.
C) with each generation, the rats' offspring made more errors.
D) with each generation, the rats' offspring made fewer errors.

Tryon's experiment with breeding "maze-bright" rats demonstrated that selective breeding for a specific trait, in this case, the ability to navigate mazes efficiently, resulted in offspring that performed better in that task across generations. This showed a genetic component to the ability to learn mazes, as the offspring made fewer errors with each generation.
