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.)

A. BB, Bb, Bb, Bb

B. BB, BB, Bb, Bb

C. BB, bb, BB, bb

D.BB, BB, BB, BB,
