Practice using a Punnett Square to determine genotype and phenotype probabilities when the genotype of the parents are known.
We can complete a Punnett square to find the possible offspring genotypes. Cross: bb x BB. If we complete the cross, we find that the possible offspring can only be Bb. Offspring that have at least one B allele must be boring because the allele for boring (B) is dominant to the allele for busy (b).
