Fast forward 10 years. You are a genetic counselor and are in a room with a patient who has recently been diagnosed as a carrier of sickle-cell anemia, which is an autosomal recessive disorder. Explain to your patient what it means to be a carrier of a disease.

Expert Solution

Hello. Have you heard of genes? A gene is a code that determines the different features of all living beings. That is the skin colour, eye colour, height, hair colour, whether it's straight or curly, everything has a gene that controls such characteristics. For a particular characteristic, two genes are there in an individual. One he recieved from father and the other from mother. These genes are present in each and every cell of our body. The haemoglobin of red blood cells or RBCs in our body is also formed as a result of such genes. However in some people there can be a genetic disorder named sickle cell anemia. This is due to a defective gene Hbs which alters the shape of RBCs. But this disease is autosomal recessive type which means that only when both the genes, the one you recieved from your father as well as your mother, are Hbs type, then the disease will manifest. You are a carrier for this disease because you have only one Hbs gene and are normal. However there is a chance that your children can have the disease depending on the genetic build up of your partner. Hence it is advised to undergo some tests before you plan to have kids.

You are a genetic counselor. As a genetic counselor, you know: -Dry (as opposed to wet) earwax is an autosomal recessive trait. -Red-green colorblindness is an X-linked recessive trait. -Sickle-cell anemia is an autosomal recessive trait. -The genes for these traits (see above) are located on different chromosomes. You are counseling a woman and a man, as described below. Question A. The woman is heterozygous for wet earwax. She has red-green colorblindness. What is the woman’s genotype? Question B. What...

You are a genetic counselor and the year is 2035. All of the CRISPR technologies have become safe and reliable for therapeutic use in humans. One of your patients presents a wasting disease where they fail to produce enough collagen in their bones. You find no mutations in the coding region of the collagen gene and the protein is at healthy levels in all other tissues. Fully explain the steps that you would suggest to treat the disease, including what...

As a counselor how would you react to this statement? You are the counselor, and the client is so attractive that you recognize that it is influencing you in your attention and responses. The issue she presents is one that you are especially capable of addressing as you have helped many others through the emotional pain.

At your job as a genetic counselor, your client is a distraught young woman. She explains to you that her mother has blood type A, her father has blood type AB, and she has blood type O. She has been told that this is not genetically possible. Your initial suspicion in this case is that there was infidelity (i.e. her father is not really her father), but the young woman refuses to accept this explanation. For her sake, you agree...

For each, whether they illustrate forward, or reverse, genetic approaches, and explain why you made that choice. A.Your graduate student read a paper in which mutations in a specific antioxidant gene leads to resistance to the biological effects of cocaine in mice. She decides to use Cas-CRISPR to make a targeted mutation in the Drosophila homolog of this gene and examine the effects of cocaine on the resulting mutant flies. Is this a forward or reverse genetic approach? B. Your...

1.1 Maria is a genetic counselor and has a son who looks very much like her. Total strangers often say “He is your little clone—he looks just like you!” She’s tempted to retort, “No he’s not! You obviously don’t know anything about genetics!” but instead just says “Thank you.” a. Based on what you know about genetics explain why Maria’s son could not be her clone. b. Would it be legal to for Maria to make a clone of herself?...

Examining Genetic Alleles in Fast-Twitch Muscles A study examines the ACTN3 genetic alleles R and X, also associated with fast-twitch muscles. Of the 436 people in this sample, 244 were classified R and 192 were classified X. Does the sample provide evidence that the two options are not equally likely? a) Conduct the test using a chi-square goodness-of-fit test. Include all details of the test. (Open-ended, typed answer) b) Conduct the test using a test for a proportion, using H0...
