Inheritance and genetic crosses

In mice, the allele for black fur ( $B\text{B}$ ) is dominant to the allele for brown fur ( $b\text{b}$ ).

A homozygous dominant black-furred mouse was mate-crossed with a homozygous recessive brown-furred mouse.

Complete the Punnett square to show the genotypes of the offspring.
