a.
To determine: The probability that the child will have cystic fibrosis.
Introduction: Cystic fibrosis is a genetic disease often affecting the lungs and also the pancreas, liver, kidneys, and intestine. The long-term effects involve difficulty in breathing and coughing up mucus as a consequence of repeated lung infections.
b.
To determine: The chance that the children will have the precise Mendelian ratio of 3:1 for normal cystic fibrosis.
Introduction: The Mendelian ratio exists of several
c.
To determine: The probability that their next three children will be normal, if their first child has cystic fibrosis.
Introduction: Cystic fibrosis is a continuous genetic disorder that induces persistent infections in the lung and restricts the strength to breathe over time. In people with CF, mutations within the transmembrane of cystic fibrosis conductance regulator gene cause the CFTR protein to become dysfunctional.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D. Plasmodium falciparumarrow_forward
