The human blood group is determined by a gene I. It has three alleles IA, IB, and i. If a person having alleles IA and IB, both genes are express completely resulting into a new

Answer to Problem 14A
Correct answer :
The correct answer is option (B) is codominance and multiple alleles.
Explanation of Solution
Explanation/justification for the correct answer :
Option (B) is codominance and multiple alleles.The human blood group is determined by a gene I. It has three alleles IA, IB and i (multiple alleles). If a person having alleles IA and IB are present, thenboth genes are express completely. The alleles IA and IB are codominant.Thus, the correct answer is option (B).
The explanation for the incorrect answer :
Option (A) incomplete dominance and codominance. In incomplete dominance both alleles blend to give new phenotype. Thus, this is an incorrect option.
Option (C)incomplete dominance and multiple alleles. A human blood group type is a case of multiple alleles but not incomplete dominance. Thus, this is an incorrect answer.
Option (D) codominance and epistasis. Human blood group types is a case of multiple allele inheritance pattern but not epistasis. Thus, this is an incorrect answer.

- A 25-year-old woman presents to the emergency department with a 2-day history of fever, chills, severe headache, and confusion. 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.
