SCIENCE, TECHNOLOGY, AND SOCIETY Imagine that you are a genetic counselor. What advice or suggestions might you give in the following situations? (a) A couple has come for advice because the woman had a sister who died of Tay-Sachs disease. (b) A young man and woman who are not related are engaged to be married. However, they have learned that the mans parents are first cousins, and they are worried about the possibility of increased risk of genetic defects in their own children. (c) A young womans paternal uncle (her fathers brother) has hemophilia A. Her father is free of the disease, and there has never been a case of hemophilia A in her mothers family. Should she be concerned about the possibility of hemophilia A in her own children? (d) A 20-year-old man is seeking counseling because his father was recently diagnosed with Huntingtons disease. (e) A 45-year-old woman has just been diagnosed with Huntingtons disease. She says she will not tell her college-age sons because of the burden it will place on them. Given that the woman, not her sons, is your client, do you have a duty to inform the sons? Explain your reasoning.

As a genetic counselor, you may face some ethical dilemmas.Imagine that a couple came to your office to discuss potential color blindness in their children.The man is not color blind, but his wife is. They already have one daughter that is color blindand want to know the probability of future children having the disorder. First, you will need toexplain to the couple the difference between sex chromosomes and autosomal chromosomes andthat color blindness is caused by a recessive mutation in a gene found on the X chromosome.Once they understand this, you can then explain to them the probability of other offspring havingthe disorder. What is the dilemma in this case and why might you need to suggest to the couplethat they see a marriage counselor
