Juliet and Bob Have Two Children, Jack and Norma

Essay

Juliet and Bob have two children, Jack and Norma. No one in this family is red-green color blind, although Juliet sometimes has difficulty passing the color-vision part of the driving test. Norma has a color-blind son with Tom, who is not color blind. Draw a pedigree that includes all of this information. Below each person in the pedigree, write his or her genotype for the red-green color blindness gene, using B for the normal allele and b for the color blindness allele.
