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?arrow_forwardA 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_forwardThe following family has a history of inherited breast cancer. Betty (grandmother) does not carry the gene. Don, her husband, does. Dons mother and sister had breast cancer. One of Betty and Dons daughters (Sarah) has breast cancer; the other (Karen) does not. Sarahs 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 Dons 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?arrow_forward
- If you knew that a devastating late-onset inherited disease runsin your family (in other words, a disease that does not appearuntil later in life) and you could be tested for it at the age of 20,would you want to know whether you are a carrier? Would youranswer be likely to change when you reach age 40?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.

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.
