This questiоn fоllоws the inheritаnce of аn аutosomal recessive lethal disease caused by a mutation in the gene R. Individuals affected with the disease develop severe neurological degeneration during adolescence and do not survive past the age of 20. The condition is rare in the general population but occurs with a higher frequency in individuals descended from the Tarahumara people of northern Mexico. A 28-year-old woman named María, whose paternal uncle died of the disease, is concerned about her genetic risk and wants to assess the probability that she and her 30-year-old husband Luis could have a child affected by the disorder. Luis’s sister died at age 14 of the same disease. María’s mother does not come from a high-risk population. Part A. (12 points) Draw the pedigree using the appropriate symbols/notation, including generations (1 point), individuals in the pedigree and the genotypes next to each symbol. ALL individuals that are identified AND confirmed as carriers must have a half-shaded symbol. Affected individuals must have full-shaded symbol. The pedigree should ONLY include the following and in the specified order: The pedigree should ONLY include the following and in the specified order: Generation I: María’s paternal grandmother and grandfather (2 individuals). (2 points). Generation II: María’s uncle and father, Marías mother, and Luis’ parents (5 individuals). (5 points). Generation III: María, Luis, and Luis’s sister (3 individuals). (3 points). Generation IV: Luis and María’s future child (1 individual, sex unspecified (use diamond shape), genotype unknown=?). (1 point). Part B. (8 points) Determine the probability that the couple’s child will be affected (follow the order below). Show your calculations and Punnet squares (if needed) in order to calculate: Probability that María’s father is a carrier . (2 points). Probability that María is a carrier (Hint: This can be found by the probability that María’s dad passes the recessive allele assuming he is a carrier).(. (2 points) Probability that Luis (María’s husband) is a carrier (2 points) Overall probability that María and Luis’ child will be affected (Hint: You will need the probability that María has the mutation, the probability that Luis is a carrier, and the probability of each parent passing the affected allele). (2 points) Show both sides of each of your papers to the camera before submitting and exiting the Exam. Do not forget to show your work for your questions on the scratch paper(s).
100 аdults between аges 55 аnd 75 participated in a study aimed at reducing the incidence оf the skin rash Shingles. The dоctоrs believe that those working full-time jobs have increased stress levels and thus, are more susceptible to the disease. The subjects either worked full-time jobs or did not, and they either received the Shingles vaccine or a placebo. For simplicity, assume that there were 25 adults in each category. The incidence rates of Shingles in each group is compared after 6 months. The response in this study is ______________.
