Travis and Marcy, a Caucasian couple, are pregnant with their first child. Travis has a prior child with cystic fibrosis (autosomal recessive). He has refused to pursue carrier testing but Marcy has had negative carrier testing. Note: Carrier testing can identify 90% of carriers of CF accurately and approximately 1/25 Caucasian's are carriers of CF. What is the chance they will have a child with CF?

Q1: Which of the children in this Punnett square represents Zoe? What is her genotype? Q2: If Zoe’s parents had another child, what is the probability that the child would have cystic ﬁbrosis? That the child would be a CF carrier? Q3: If Zoe is able to have a child of her own someday, and the other parent is not a carrier of cystic ﬁbrosis (he would likely be tested before they chose to have children), what is the probability that the child would have cystic ﬁbrosis? That the child would be a carrier?

The following scenario can be seen on Ch 29 Clinical case study on Heredity (27-year-old with normal pregnancy): Mrs. Rodriguez’ blood type is type O, and her husband’s is type A. She is currently pregnant and she would like to know what type of blood her baby will have. For discussion 7 please answer the following questions: What are the genotype and phenotype of Mrs. Rodriguez? What are the genotype and phenotype of Mr. Rodriguez, given that Mr. Rodriguez’s mother has O blood type and his father has A blood type? (use Punnett Square on your worksheet to find out the genotype of Mr. Rodriquez) What is the probability that Mrs. Rodriguez’s baby will have O blood type? A? B? AB? (use Punnett Square as your worksheet) Type O =______% Type A = _____ % Type B =______% Type AB =______%
A woman who is a carrier for hemophilia marries a normal man. What is the probability that their first child will be a hemophiliac girl? What is the probability that the child will be a girl who is a carrier for the disease? What is the probability that, if they have a son, he will be normal? What is the probability that they will have a son who is a carrier for the disease?
