Textbook Question
Chapter 12, Problem 17QP
The following family has a history of inherited breast cancer. Betty (grandmother) does not carry the gene. Don, her husband, does. Don’s mother and sister had breast cancer. One of Betty and Don’s daughters (Sarah) has breast cancer; the other (Karen) does not. Sarah’s daughters are in their 30s. Dawn, 33, has breast cancer; Debbie, 31, does not. Debbie is wondering if she will get the disease because she looks like her mother. Dawn is wondering if her 2-year-old daughter (Nicole) will get the disease.
- a. Draw a pedigree indicating affected individuals and identify all individuals.
- b. What is the most likely mode of inheritance of this trait?
- c. What are Don’s genotype and
phenotype ? - d. What is the genotype of the unaffected women (Betty and Karen)?
- e. A genetic marker has been found that maps very close to the gene. Given the following marker data for chromosomes 4 and 17, which chromosome does this gene map to?
- f. Using the same genetic marker, Debbie and Nicole were tested. The results are shown in the following figure. Based on their genotypes, is either of them at increased risk for breast cancer?

Do you think Kay’s cancer is inherited or sporadic? Why? (1-2 sentences only)
Three people are diagnosed with different types of cancer. One is a lifelong smoker and has lung cancer,
one has active Crohn disease and colorectal cancer, and the other is a farmer with newly diagnosed
melanoma. What do these individuals have in common?
K.S. comes for a clinic visit to determine whether she is pregnant. She is very concerned because she suspects there may be a genetic disease in her family. On further questioning, you find out that her brother’s son has the disorder. Her brother’s other children (a boy and a girl) are unaffected. K.S.’s parents, grandparents, and other siblings (a brother and two sisters) do not have manifestations of the disorder. Her brother’s wife has said that she thinks one of her distant relatives may have had the disease.
Discussion Questions
If the disorder is indeed inherited as a single-gene defect, do you think it is autosomal dominant, autosomal recessive, or X linked? Justify your answer.
Construct a pedigree chart and predict the likelihood that K.S. has the defective gene.

- A couple has had a child born with neurofibromatosis. They come to your genetic counseling office for help. After taking an extensive family history, you determine that there is no history of this disease on either side of the family. The couple wants to have another child and wants to be advised about the risks of that child having neurofibromatosis. What advice do you give them?arrow_forwardA couple has one child with bilateral retinoblastoma. The mother is free from cancer, but the father has unilateral retinoblastoma and he has a brother who has bilateral retinoblastoma. a. If the couple has another child, what is the probability that this next child will have retinoblastoma? b. If the next child has retinoblastoma, is it likely to be bilateral or unilateral? c. Explain why the father’s case of retinoblastoma is unilateral, whereas his son’s and brother’s cases are bilateral.arrow_forwardA woman who is eight (8) weeks pregnant requests a direct test for Huntington’s disease on her fetus. She tells her geneticist that she wants the test because she recently discovered that there is a family history of the disease in her husband’s family. One of his parents is affected so he is at 50% risk of developing the condition. She is adamant that she does not want to give birth to a baby who is at risk of developing Huntington’s and says that the test will help her to ensure that this is not the case. In counseling, she reveals that she has discussed this issue several times with her husband but he has always said he is not willing to take a test. He does not want to know his status and is extremely anxious about the possibility that he might develop the condition. The woman and her husband are currently separated but are seeing a relationship counselor and trying to work things out. Despite this, the woman says they tend to fight a lot. When it is explained to her in counseling…arrow_forward
- Jonah and Jana are siblings. Jonah has the genetic disorder cystic fibrosis, caused by inheriting two mutant alleles of the CFTR gene (the gene that when mutant causes cystic fibrosis) - one allele was inherited from each parent. Jana does not have cystic fibrosis. Which of the following statements is/are true? Jana does not have the CFTR gene. Jana has two copies of the CFTR gene. Jana has at least one copy of the non-mutant allele of the CFTR gene. Jana has two copies of the mutant allele of the CFTR gene.arrow_forwardAchondroplasia is a form of dwarfism in humans. It is caused by a mutant allele of the fibroblast growth factor receptor 3 gene ( FGFR3) that produces an overactive protein. Having one copy of the mutant allele results in dwarfism. Two copies of the mutant allele results in death before birth. If a man with Achondroplasia marries a woman who is Sickle Cell Anemia carrier and they have a child together, what is the probability that their child will Achondroplasia AND be a Sickle Cell Anemia carrier? ½ 2/3 ¼ 1 ½ 1/16arrow_forwardJ.F. is a 26-year-old woman in the clinic today for her annual physical examination. As you take her medical history, it becomes apparent that she is quite concerned about her risk for developing breast cancer. Her mother and a maternal aunt both developed breast cancer in their late 40s. J.F. has heard that genetic testing can be done to see whether she carries “breast cancer genes.” What proportion of breast cancer cases can be attributed to inherited forms? What other cancer would J.F. be at risk for given the presence of the BRCA1 gene? How significant is that risk?arrow_forward

If so, when would you want to be tested? As a teenager or sometime in your 40s?

The woman’s mother had sickle cell anemia and her father was a carrier of the sickle cell gene. The man knows that he is not a carrier of the sickle cell gene. What is the probability that the child will be a carrier of sickle cell anemia?arrow_forward
- 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.arrow_forwardDivya is 32 years old. She has found a small lump in her left breast and decided to go to her GP for a check-up. Her GP examined her and asked whether terse was any family history of cancer. She said her sister had breast cancer and he mother had died of ovarian cancer. Divya said there were also cases of cancer within her extended family. The pedigree below shows 3 generations of Divya’s family. The GP analysed the pedigree and concluded there was likely to be an inherited mutation running through Divya’s family and immediately referred her for a mammogram and a biopsy of the lump. Tissue from the biopsy was set for gene testing. Part 1 What type of inherited cancer syndrome appears to be present in Divya’s family? Part 2 What is the name of the gene being tested for matrons and what gene class does it belong to? Part 3 Are inherited mutations in this gene loss of function, gain of function or silent? Would you expect an individual to inherit a mutation in both parental copies of this…arrow_forwardA male presenting with clinical features as greater height, poor coordination, less body hair, breast growth and seems less interest in sex.
