Summary Introduction
To determine: The person who cannot be the father of a child with the given blood groups of mother and child.
Introduction: Human blood group is an example of codominance. A gene has two pairs of alleles that are either dominant or recessive. Usually, in heterozygotes, the dominant allele masks the expression of a recessive allele, and so only the dominant allele is expressed. Codominance is a type of dominance in which both the alleles of a heterozygous gene are coexpressed resulting in a trait that is neither dominant nor recessive.

The identity of Kim's biological father is unknown, but it is thought to be either Kevin or Thomas. To determine which of the two men it is, blood typing of all the persons involved was performed.
Here are the results of the blood tests, including the phenotypes and possible genotypes of each person:
Rachel (mother) Type AB; genotype IA, IB
Kim (child) Type A; genotype is either IA, IA (if homozygous) or IA, i (if heterozygous)
Kevin (alleged father #1) Type A; genotype is either IA,IA if homozygous or IA, i if heterozygous
Thomas (alleged father #2) Type O; genotype is ii
There are 2 DNA bands in the "fingerprint" of each person tested: mother, child, alleged father 1, and alleged father 2. Why are there two bands for each person and not three?
Hemophilia is inherited as a sex-linked recessive trait. A non-hemophilic man marries a non-hemophilic woman whose father had hemophilia.
With respect to this information, indicate all possible genotypes their children could possibly have.
Show ALL work using punnett squares.
In a well-publicized paternity case, the following facts were determined: the mother, a beautiful, twice-convicted axe murderer, is blood type A. Her child, Lizzie, is type O and the alleged father, a mild-mannered felon convicted of check fraud, is type B. On the last day of the trial, another father – a missionary worker with blood type O is identified. Which of the two could be Lizzie’s father? Use the space below to support your conclusion.
I am really confused with the queshtion and need help finding the answer and how to prove can somone explain the answer and show it in a punnet sqaure please
