Question
What percentage of the F2 offspring predicted in a cross for mice coat color
In mice, the allele for black fur is dominant to the allele for brown fur. If a male homozygous black mouse is crossed with a female brown mouse, what percentage of the F2 offspring do you predict will be homozygous?

Since both parents have to be homozygous, all of F1 will be heterozygous (Bb).
