In certain wild animals with normally black fur there occurs a very strange kind of coloring that is known as agouti. Each hair in the fur is black, but just below the tip, the hair has a band of yellow. With thousands of these yellow bands the fur of the animal does not look black. It has a mousy brown color. A strain of pure agouti mice was crossed with pure black mice. The result was ALL agouti mice. When the P2 offspring agouti mice were crossed with each other, the resulting offspring showed three times as many agouti mice as black mice. Which trait is dominant? Black Agouti white cannot be determined
