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

Do a Punnett square for F2.
