In mice, black fur is dominant to grey fur. If you cross a BB male with a Bb female, what are the possible genotypes and phenotypes of the offspring? What is the percent chance for each type?

50% BB (black), and 50% Bb (black)

Explanation:

When you make the punnet square, you will get two BB, and two Bb. That will show you that the outcome of all the offspring will be black. There is 0% chance there will be a grey mouse because it is the recessive gene.
