The ABOblood group gene has three alleles, with IA and IB codominant, and i recessive. The Rh blood group gene has only two alleles, with the Rh+ phenotype (Rallele) dominant over Rh–(rallele). Finally, the MNblood group gene has two codominant alleles, Mand N.A child has blood types B, Rh–, and M. His mother has blood types O, Rh+, and MN. Give the genotype of the mother, and the possible genotypes of the father

The ABO blood group assorts independently of the Rhesus(Rh) blood group and the MN blood group. Three alleles,IA, IB,and i, occur at the ABOlocus. Two alleles, R, a dominant alleleproducing Rh+, andr, a recessive allele forRh?, are found at the Rh locus, and codominantalleles M and N occur atthe MN locus. Each gene is autosomal.


A child with blood types B, Rh+, and M is born to a womanwho has blood types O, Rh?, and M and a man who has blood types AB,Rh+, and M.
Determine the genotypes of each parent.

Mother's blood type is: ii rrMM


A) What is the father

1. This question refers to the ABO blood type locus. Rememberthat the A and B alleles are codominant to each other and both aredominant to the O allele. Assume no epistaticinteractions with the H locus.

A man has blood type B. Mark all genotypes below that arepossible for this man.

Select one or more: AA, AB, AO, BB,BO, OO

2.This question refers to the ABO blood type locus. Rememberthat the A and B alleles are codominant to each other and both aredominant to the O allele. Assume no epistaticinteractions with the H locus.

A woman is blood type B. Her child is blood type AB. She wantsto get child support from a man who is blood type A. Can this manbe the father of the woman's child based on these data?

Select one:Yes/No

3. This problem refers to the MN and ABO loci mentioned inclass. It also refers to the Rh locus, which is responsible for thepositive/negative part of the blood type. The Rh+ allele isdominant to the Rh- allele at this locus. Select all couples whocould be the parents of a child with phenotype M, AB- based on thephenotypes at these three loci. If none of these couples could bethe parents of this child, select "None of These".

Select one or more:

Mother Type M, A+ and Father Type N, B-

Mother Type MN, AB- and Father Type M, O-

Mother Type MN, B+ and Father Type N, O+

Mother Type MN, O+ and Father Type MN, A-

None of These

In addition to the ABO self-antigen system, another red blood cell self antigen system is the Rh factor. The gene for this self-antigen system exhibts complete dominance with Rh positive being completely dominate over Rh negative. Rh positive is symbolized as + and Rh negitive is symbolized as -. Geraldo has B- blood and Arline has O+ blood. Geraldo's father had B+ blood and his mother has O- blood. Arline's mother has O- blood and her father has A+ blood. Geraldo and Arline have a daughter, Elise. Construct a Punnett square of the mating between Geraldo and Arline.

What are the possible blood types for Elise?

What id Geraldo's genotype?

What is Arline's genotype?
