The ABO blood group system is valuable in helping to settle cases of disputed parentage. The following table lists the blood types of various mother-child combinations. In each case list the blood types that can be excluded as possibilities for the father.
| Blood type of child | Blood type of mother | blood types that father cannot have |
| O | O | |
| O | B | |
| A | B | |
| B | O | |
| AB | A | |
| AB | B |

a.) ABO blood types are determined by a single gene with 3 alleles. Alleles A (IA) and B (IB) are co-dominant to allele O (i). Cecilia, a woman with blood type A whose father and mother both had blood types AB, marries a man named Joseph. Joseph has blood type B. Joseph’s mother had blood type O. What is Cecilia’s genotype with respect to blood type? b.) ABO blood types are determined by a single gene with 3 alleles. Alleles...

Analyzing Genetic Data A. ABO Blood Group The human ABO blood group is an example of how three alleles that control a trait may interact. In this case, two of the alleles are codominant and one is recessive to the other two. The table below lists the phenotypic and genotypic data for this trait. Blood Type Phenotype Type A Type B Type AB | Type 0 Possible Genotype Ilori Pori | IAI 1. List the three alleles that control expression...

8 A case of disputed paternity involves a woman, her children (1, 2 and 3), and two men Y and Z). The analysis is limited to the ABO and Rh blood group systems. Using the space below, and assuming that only YorZ could be the biological father, assign each child to his/her possible father. You can use either Punnett squares for each trait, or the process of Mother Possible Fathers Children Possible father for each child elimination. There may be...

Children’s ABO blood types are dependent on their biological parents’. ABO blood type; each parent provides one allele from which a fetus from its ABO blood type. Here is a list of all possible alleles received and their corresponding ABO blood type. Alleles AA AO AB BB BO OO Blood type A A AB B B O If two babies were born to this couple, what is the probability that the ABO blood types are A for both children A...

A and B are codominant over O in the ABO blood system. Another common way to type blood is with the Rh factor, in which Rh positive is dominant over Rh negative. A toddler has B positive blood. The mother has A negative blood. Potential father #1 has O positive blood. Potential father #2 has B negative blood. Potential father #3 has AB positive blood. Who is the child's father and why?

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 MN, O+ based on the phenotypes at these three loci. If none of these couples could be the parents of this child, select "None of...

With regard to the ABO blood types in humans, determine the genotypes of the male parent and female parent: (a) Male parent:blood type B whose mother was type O, (b) Female parent:blood type A whose father was type B, (c) Predict the blood types of the offspring that this couple may have and the expected ratio of each.
