Chapter 1, Problem 9QP
If your father were diagnosed with an inherited disease that develops around the age of 50, would you want to be tested to find out whether you would develop this disease? If so, when would you want to be tested? As a teenager or sometime in your 40s? If not, would you have children?

Why shouldn't genetic testing be mandatory for those planning on having children?
Do you agree or disagree why?
I think this topic is sort of tricky and I still can't decide if I feel like we should allow this. I think there many good pros as well as cons when it comes to changing a babies genes and traits. I understand why people would want to make sure their baby is born healthy and doesn't have any diseases like Alzheimers or Huntington's disease. At the same time, I am a big believer in the idea that everything happens for a reason so part of my feels like it is wrong to alter a baby because you never know what life could've been like. ( I hope what I am trying to say makes sense) There is also that risk of the baby getting more sick and other things happening which makes me feel like it is not worth the risk to alter them. In the article I read it mentions how this can make people superior to others which I also think will cause some problems in the future.

They are/are not passed on to offspring. Inherited cancers are more/less common than sporadic cancers. Do you think Kay’s cancer is inherited or sporadic? Why? (1-2 sentences only)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

Support your answer in 3-4 sentences. only 3-4 sentences thank you.arrow_forwardThree 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?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
- The father of five children begins to show symptoms of huntington disease. what is the probability that same, the man's second oldest son (11-2),, will suffer from the disease if he lives a normal life span? Sam's mother and her ancestors do not have the diseas. Sam's father was adopted, so we do not know his biological family history for hunutington disease. Explore all possible outcome for sam and explain your reasoningarrow_forwardYou met with two parents whose first child has sickle cell anemia. (The parents show no signs of the disease themselves). The mother comes to you in the third month of her second pregnancy, and wants to know if this child will also inherit the disease. As a genetics counselor, you are ready to evaluate this couple’s case by doing the following:1. Determine what the genotype of each parent is. Is this disease autosomal or sex-linked? Dominant or recessive?arrow_forwardBoth parents love strawberry blonde hair but hate the fact they can touch their noses with their tongues. What are the odds their child will be a strawberry blonde non-nose touching individual?arrow_forward
- The father of three sons and two daughters begins to show symptoms of Huntington disease. What is the probability that Sam, the man’s second oldest son (II-2), will suffer from the disease if he lives a normal life span? Sam’s mother and her ancestors do not have the disease. Sam's father was adopted, so we do not know his biological family history for Huntington disease. Explore all possible outcomes for Sam and explain your reasoning. What about the risk to Sam's sisters? Would that be the same or not?arrow_forwardAlex 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.arrow_forwardIf a mother and father have a son who has a dominant disease like Marfan syndrome, but they both do NOT (they are healthy), would would the Punnett square look like for the parents? What can we conclude about the health of their son from this?arrow_forward
