A woman with blood type B-neg has a daughter who is O-pos and a son who is type A-neg with her husband. Rh is positive is a trait that shows simple dominance over Rg negative. ABO represents a gene with three alleles, two of which are codominant (A and B) and one recessive (O).

a.) What is the genotype of the son?

A. AB B. AO C. BO D. AA E. A, B AND D ARE POSSIBLE

b.) What is the phenotype of the father?

A. O pos B. A pos C. A neg D. B neg e. AB neg

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

There are also traits that have more than two alleles, one example of which is the ABO blood system that determines your dominant blood type. Most of you should know what type of blood you are. In the ABO blood system alleles A and B are co-dominant, and the O allele is recessive to A and B. Blood type A (phenotype) is found in individuals with genotypes AA or AO, while blood type B is found in individuals with genotypes BB or BO. The "O" blood type is only found in individuals with the genotype OO, and the blood type AB can ONLY be found in an individual with the genotype AB.

In this series of questions, you are working as a technician for the Maury Povich television show, and you need to determine the paternity of Sheila's baby. Sheila has blood type AB.

The first candidate for the father, Tony, has a known blood type of AO (type A blood). Which of the following Punnett squares illustrates the possible blood types of Sheila and Tony's offspring?

The ABO blood 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 (R allele) dominant over Rh–(r allele). Finally, the MN blood group gene has two codominant alleles, M and 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.
