Chapter 14: Mendel and the Gene Idea There are tests to identify carriers that allow couples with a family history of a disorder to make informed decisions about having children. Genetic counseling for these families is based on Mendelian genetics and probability rules. Work through the example of hypo- thetical couple Tyler and Lily on p. 288 of your text to understand the mathematics involved. Then, solve the following problems. 37. Lucia and Jared each have a sibling with cystic fibrosis; neither Lucia or Jared nor any of their parents have the disease. Calculate the probability that a child born to this couple will have cystic fibrosis. Show your work and explain your answer. a.
