Consider the following genetic problem dealing with cystic fibrosis, which is a recessive trait (disease). We will use B to represent the normal allele, and b to represent the mutated allele responsible for cystic fibrosis. If a woman who is a heterozygous for the alleles has children with a man who is homozygous normal, what is the predicted genotypes based on analysis by a Punnet square? (Do the Punnet square and the outcome will be indicated using the results in the boxes.)
