Chapter 19, Problem 10CT
Bill and Marie each have flat feet, long eyelashes, and “achoo syndrome” (chronic sneezing). All are dominant traits. The genes for these traits each have two alleles, which we can designate as follows:
Bill is heterozygous for each trait. Marie is homozygous for all of them. What is Bill's genotype? What is Marie’s genotype? If they have four children, what is the probability that each child will have the same
