Bioethics Case Study Sickle cell anemia is a genetic disease caused by a mutation in the beta-globin gene responsible for producing an important subunit of hemoglobin. People that have 2 copies of the mutation have the disease, and those that have 1 copy do not have the disease but are considered “carriers”. At the molecular level, abnormalities in the hemoglobin protein cause it to clump, which leads the red blood cells (rbcs) that carry hemoglobin to become misshapen. As a result, the rbcs cannot bind oxygen as efficiently and the body is deprived of oxygen (anemia). The abnormally shaped rbcs also slow down blood flow and become clogged in narrow blood vessels, causing pain. There is no cure for sickle cell anemia, and the goal of treatment is to manage symptoms. Robin, a 30-year-old female, is a carrier for sickle cell anemia. She recently married Brent, who is also a carrier for sickle cell anemia. They want to start having kids immediately but cannot afford the invasive and expensive assisted reproductive technologies that would ensure them a baby without sickle cell anemia. If they decide to have children naturally, they will have a 1-in-4 (25%) chance of producing a child with the disease. Robin has close relatives who suffer significantly with sickle cell anemia, and she does not want to bring a child into the world with the same difficult fate. Brent is more optimistic and takes the view that they have a 3-in-4 (75%) chance of producing a child that does NOT have sickle cell anemia. Robin does not want to “play the odds” and would prefer to adopt, while Brent feels strongly about having a biological child. Which of the following is an ethical question raised here? [1] Which of the following is a relevant scientific fact to this ethical question? [2] Which of the following is not a stakeholder in how this ethical question gets resolved? [3] Which of the following is not paired with the correct relevant ethical consideration? [4]

When a direct-to-consumer genetic testing companies performs Late-Onset Alzheimer’s genetic testing they perform [1], to determine your [2] for Alzheimer’s. However, studies have found that testing companies use different tests and calculations to determine your results, and can produce false positives. Accurate and reliable test results are important and are described as [3], while whether these results are of significance in the disease is referred to as [4].

A yeast strain was exposed to a chemical mutagen. As expected, exposure to mutagen resulted in a DNA sequence change in an essential gene (required for survival) you examined. Yet this mutation did not result in any lethal phenotype (cause death). Which of the following answers would BEST explain this apparent discrepancy?
