The possible method to handle the scenario in which an individual should contact the proband beforehand to explain the results and the implications of the results. Introduction: A couple has undergone a prenatal test in which the young woman (proband) is found to have the sickle cell trait (Ss), and her partner does not have the sickle cell anemia (SS). The woman’s family has a family history of sickle cell anemia. Their prenatal tests indicate that the fetus is affected with sickle cell anemia (ss) and the only way it is possible is when the woman’s partner is not the father of the fetus.

As a genetic counselor, you are asked to assess the risk for a couple with a family history of familial adenomatous polyposis (FAP) who are thinking about having children. Neither the husband nor the wife has colorectal cancer, but the husband has a sister with FAP. What is the probability that this couple will have a child with FAP? Are there any tests that you could recommend to help in this assessment?

The gene for polydactyly (P) is autosomal and dominant to normal fingers (p). Hemophilia is sex-linked and recessive (X h ). A man and his wife both of whom are polydactylous and have normal red blood cells have a child who is non-polydactylous and with hemophilia. What are their genotypes?
