A researcher who has pioneered cell-free fetal DNA testing to detect trisomies has received threats from people accusing her of killing babies. She counters that the test will save lives. How can cell-free fetal DNA testing save lives? What impact do you think the wider availability of early, safe, and accurate testing for trisomy 21 Down syndrome will have on society? Discuss views that might come from a pregnant woman and her partner, a parent of an adult child with Down syndrome, and a physician who offers prenatal testing.

Create a hypothetical person and situation as a real life example to illustrate your position. Who is this person? How old is this person? What chromosomal abnormalities does this person have? How does genetic testing and counseling make this person’s life better or worse? Ultimately, should your hypothetical person seek genetic counseling?
Imagine that you are in your late 30s or early 40s and decide that you want a child. You realize that you’re at greater risk of having a child with Down’s Syndrome. What sorts of genetic screening are available today? If you find out that this child has this condition, do you think it’s appropriate to have an abortion? Why or why not? Question: Does elective abortion of fetuses with physical or other developmental disabilities have an effect on the perception of personhood, dignity, and rights in society? Explain.
A type of red-green colorblindness is inherited recessively on the X chromosome. A woman who is a carrier had children with a male that is not affected by the disease. Show your answers with the use of a Punnett square • What is the probability (% or likelihood) that a child is affected by the disease? • What is the probability (% or likelihood) that a son is a carrier? (Careful!) • Is there a chance that a girl of the couple is affected by the disease?
Alex is newly pregnant with twins and curious about everything about her developing children. Her doctor was able to tell her that her twins are dizygotic twins via ultrasound. In your essay, describe the difference between monozygotic and dizygotic twins and explain how each is conceived. Alex is also wondering about the genetics of her children and how they will act when they are older. Offer an explanation of genotype and phenotype and provide an example of each specific to Alex’s future children being dizygotic twins. Finally, in your previous explanation be sure to also describe how most traits are both polygenic and multifactorial and how that may influence her twins’ phenotypes.
Why shouldn't genetic testing be mandatory for those planning on having children?
Hereditary hemochromatosis is an autosomal recessive genetic disorder that causes the body to absorb too much iron from the diet. This excess iron is stored in the body's tissues and organs, particularly the skin, heart, liver, pancreas, and joints. Because humans cannot increase the excretion of iron, excess iron can overload and eventually damage tissues and organs. A man who had hemophilia (an X-linked recessive genetic disorder), married a woman who had no family history of hemophilia whatsoever. The couple had consulted a genetic counselor when they first contemplated having children due to concerns that their future children might have hemophilia. Genetic testing of both future parents revealed that the husband did, in fact, possess the Hemophilia A allele but his wife was completely normal with respect to hemophilia. Much to their shock, their first child, a daughter, had a mild blood clotting disorder. Karyotyping was performed to determine whether this daughter had an…
Which three factors are crucial in the diagnosis of genetic defects in the fetal stage? What do you think weighs the most?
A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a man who suffers with hemophilia. What is the probability that their first daughter will have hemophilia?
Suppose gene B is X-linked and is embryonically lethal when homozygous or hemizygous recessive. A man marries a woman who is heterozygous for this gene. They want to have three kids – one girl and two boys. Using a Punnett square, answer the following: What is the probability that they will have a son that dies before birth? _______________________ What is the probability that they will have a daughter who has the same genotype as her mother? _________________ One of their daughters eventually has a child with a man. One of their sons dies before birth. What was the genotype of this daughter? _______________________________ please show me how to get the answer and explain how you got and use a punnet square
A mother who is heterozygous for Huntington’s disease (child from mother in #8) and a father who is homozygous normal want to have a baby. What genotypes and phenotypes are possible for their child?
Jan is concerned about using ART. She wants to be the genetic mother and have Darryl be the genetic father of any children they have. What methods of ART would you recommend to this couple? Jan, a 32-year-old woman, and her husband, Darryl, have been married for 7 years. They have attempted to have a baby on several occasions. Five years ago, they had a first-trimester miscarriage, followed by an ectopic pregnancy later the same year. Jan continued to see her OB/GYN physician for infertility problems but was very dissatisfied with the response. After four miscarriages, she went to see a fertility specialist, who diagnosed her with severe endometriosis and polycystic ovarian disease (detected by hormone studies). The infertility physician explained that these two conditions were hampering her ability to become pregnant and thus making her infertile. She referred Jan to a genetic counselor. At the appointment, the counselor explained to Jan that one form of endometriosis (MIM 131200) can be a genetic disorder, and that polycystic ovarian disease can also be a genetic disorder (MIM 184700) and is one of the most common reproductive disorders among women. The counselor recommended that a detailed family history of both Jan and Darryl would help establish whether Jans problems have a genetic component and whether any of her potential daughters would be at risk for one or both of these disorders. In the meantime, Jan is taking hormones, and she and Darryl are considering alternative modes of reproduction. Using the information in Figure 16.4, explain the reproductive options that are open to Jan and Darryl.
