- How might a genetic counselor help a couple determine whether or not they could have a son with hemophiliaBecause 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 100% chance that the second child will be diagnosed with beta-thalassemia major. If her parents have another child naturally, there is a 25% chance that the second child will be diagnosed with beta-thalassemia major.The mother of a family with 10 children has blood typeRh+. She also has a very rare condition (elliptocytosis,phenotype E) that causes red blood cells to be oval rather than round in shape but that produces no adverseclinical effects. The father is Rh− (lacks the Rh+ antigen)and has normal red blood cells (phenotype e). The children are 1 Rh+ e, 4 Rh+ E, and 5 Rh− e. Information isavailable on the mother’s parents, who are Rh+ E andRh− e. One of the 10 children (who is Rh+ E) marriessomeone who is Rh+ e, and they have an Rh+ E child.a. Draw the pedigree of this whole family.b. Is the pedigree in agreement with the hypothesisthat the Rh+ allele is dominant and Rh− is recessive?c. What is the mechanism of transmission ofelliptocytosis?d. Could the genes governing the E and Rh phenotypesbe on the same chromosome? If so, estimate the mapdistance between them, and comment on your result
- Hemophilia is an X-linked disease associated with the inability to produce specific proteins in the blood-clotting pathway. Shown above is a family pedigree tree in which family members afflicted with the disease are shown with filled-in squares (male) or circles (females). A couple is trying to determine the likelihood of passing on the disease to their future children (represented by the ? symbol above) because the hemophilia runs in the woman’s family 4.Assuming that the woman in the couple is a carrier, what is the probability that the couple’s first son will have hemophilia?From the powerpoint presentation, choose five (5) terms or concepts pertaining to chromosomal abnormality in the number. Describe each in a sentence. https://www.slideshare.net/farhanali911/chromosomal-abnormalities-33461290Mr and Mrs Connelly are planning to start a family. However, Mr Connelly is concerned that, as his brother was diagnosed with cystic fibrosis (CF), he may be a CF carrier. Their GP explains how Mr Connelly may carry the faulty CFTR gene using a Punnett square. create two separate Punnett squares and explain in detail the possible outcomes for the children of two different sets of parents as follows: Set A parents are both carriers of Huntingdon’s Disease, and in Set B only one parent is a carrier of Huntingdon’s Disease. Explain the results in detail of each Punnett Square
- interpret using the punnett square below to both sets of parents (Parents A , Parents B, & Parents C).based on your results of filling in the boxes. What are the chances Parents A, Parents B, and Parents C will have a child with Sickle Cell? What are the chances the child will be a carrier for Sickle Cell?You 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?Hemophilia is due to a sex-linked gene. It is recessive and found on the X chromosome. A woman who is a carrier for hemophilia marries a normal man. What will be the possible phenotypes of their children? (use the letter “H”)
- Mr and Mrs Connelly are planning to start a family. However, Mr Connelly is concerned that, as his brother was diagnosed with cystic fibrosis (CF), he may be a CF carrier. Their GP explains how Mr Connelly may carry the faulty CFTR gene using a Punnett square. create a Punnett square to show possible outcomes for their children if Mr Connelly is a CFTR carrier but his wife is not and explain the results in detail.Hello, please answer the following Biology question correctly based on the given answer choices.
