A certain couple has six children – four boys (ages 2yr, 5yrs, 9yrs and 11yrs old) and two girls (ages 5yrs and 7yrs old). The oldest boy shows the symptoms of Duchenne Muscular Dystrophy (DMD). What are the chances of their other children developing the disease?
A 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…

- Q1: Which of the children in this Punnett square represents Zoe? What is her genotype? Q2: If Zoe’s parents had another child, what is the probability that the child would have cystic fibrosis? That the child would be a CF carrier? Q3: If Zoe is able to have a child of her own someday, and the other parent is not a carrier of cystic fibrosis (he would likely be tested before they chose to have children), what is the probability that the child would have cystic fibrosis? That the child would be a carrier?arrow_forwardBecause Elsa has received a confirmed diagnosis of beta-thalassemia major, which of the following statements is true about her parents? Only her mother carried the gene that caused her blood disorder. Only her father carried the gene that caused her blood disorder.

If her parents have another child naturally, there is a 25% chance that the second child will be diagnosed with beta-thalassemia major.arrow_forwardSuppose a couple brought to you their 8-year old boy with progressive muscle weakness, and difficulty in motor skills resulting to awkward manner of walking and running . The boy’s 15-year old sister and11-year old brother appear to be unaffected. They have a normal father and a normal pregnant mother. The mother had a brother who died at 26 yrs. of age with similar findings that seemed to worsen with age. The mother also has a sister with the same findings but it only manifested during her 28 th year. Her sister, who married an unaffected man, has two affected sons and a normal daughter.You suspect a diagnosis of Duchenne Muscular Dystrophy (DMD). a. Draw the pedigree of this family. Follow protocols in making a pedigree. Provide the genotype of all individuals in the pedigree. Please provide also the gene notation. b.
