Question
Please help with explaination! Will rate highly if answer is correct and includes explaination.
This problem refers to the MN and ABO loci mentioned in class. It also refers to the Rh locus, which is responsible for the positive/negative part of the blood type. The Rh+ allele is dominant to the Rh- allele at this locus. Select all couples who could be the parents of a child with phenotype M, O+ based on the phenotypes at these three loci. If none of these couples could be the parents of this child, select "None of These".
Select one or more:
a) Mother Type M, A+ and Father Type N, B-
b) Mother Type MN, AB- and Father Type M, O-
c) Mother Type MN, B+ and Father Type N, O+
d) Mother Type MN, O+ and Father Type MN, A-
e) None of These

a. FALSE
Reason: For the son to be M,O,Rh+ , father does not have an LM allele.
b. FALSE
Reason: Both the parents are Rh -ve therefore son can never be Rh+ve.
c. FALSE
Reason: For the son to be M,O,Rh+ , father does not have an LM allele.
d. TRUE
Reason: Mother and father both have LM allele. Father can be heterozgous for antigen A (i.e, Ia Io) and the mother has an Rh+ve allele. So there is a possibility that their son can have M,O,Rh+ blood group.
PS: Feel free to comment for further clarification. Thank you.
