Question
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 N, B+ 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. None of These
c. Mother Type MN, AB- and Father Type M, O-
d. Mother Type MN, B+ and Father Type N, O+
e. Mother Type MN, O+ and Father Type MN, A-
Explanation / Answer
Answer:
d. Mother Type MN, B+ and Father Type N, O+
Explanation:
The genotype of the child blood, N, B+ =
NN IBi Rh+ Rh- or
NN IBi Rh+Rh+ or
NN IBIB Rh+Rh- or
NN IBIB Rh+Rh+
Mother Type MN, B+ (MN IBIB Rh+Rh+) x Father Type N, O+ (NN ii Rh+ Rh+) ---Partents
