Homer Simpson goes to the hospital to run some tests. The doctors there ask him what his blood type is, but unfortunately he does not know. What he does know is that Marge Simpson has type A blood, their daughter Lisa has type A blood, their son Bart has type B blood, and their daughter Maggie has type O blood. What is Homer's blood type? Make sure to show a Punnett square to justify your answer. *

A mother with blood type A has a child with blood type AB. Give all possible blood types for the father of this child. Group of answer choices   O   B, AB   A, AB   A, B, O   A, B, AB, O

b. Michael and Nora have three children: Olivia, Paul and Quentin, however Michael suspects Nora may have had an affair with his friend Leonard. He is not sure whether all the children are his. In a school project, the three kids discover that their blood groups are A, O and B respectively. Michael knows that his own blood type is AB and Nora's is A. i. Based on their blood groups, determine whether it is possible or impossible for each child to be Michael's. ii. Leonard is blood group B; determine whether it is possible or impossible for each child to be Leonard's.

A woman with type O blood gave birth to a baby, also with type O blood. The woman stated that a man with type AB blood was the father of the baby. Is there any merit to her statement?

A mother has a child and needs to prove who the father is to get child support. Looking at the following DNA fingerprint, who is the father? How did you determine who was the father? Why is it important that ALL DNA samples are cut with the same enzyme? What bands in the offspring came from which parent?

Two babies in a maternity ward have lost their identity bands, and there is some confusion about their footprint records. Baby #1 is type A blood; #2 is type B blood. If you are one of the mothers and your blood type is O, which one of the following statements applies. Explain your answer. Neither baby could be yours. The type A baby is yours. The type B baby is yours. Either baby could be yours.

A child has a blood type of “B positive”.  This child is known to be a heterozygote at the ABO blood type gene and also a heterozygote at the Rh blood type gene.  Select all of the choices below that show possible parents of this child.

From the following blood types, determine which baby belongs to which parents. Explain your answer using Punnett squares, and or written justification. Baby 1 → Blood Type O Baby 2 → Blood Type B     Mr. Smith → Blood Type A Mrs. Smith → Blood Type A Mr. Kim → Blood Type A Mrs. Kim → Blood Type AB

A couple decide to have a child. They require and select a suitable sperm donor who they understand to be blood group AB and rhesus +ve. The carrier of the baby is blood group A and rhesus –ve. However, when the baby is born, they discover that the baby’s blood group is O rhesus +ve. Worried that there has been a mistake they ask for a DNA test, which confirms the sperm used was indeed that of the donor. Further DNA analysis of the carrier of the baby shows that she has isoagglutinogen alleles IA iO, while the baby is actually IB and IO.      How would you explain the outcome of the blood group to the couple? What is the chance that any other children will be blood group O using the same sperm donor?    What further medical considerations should the couple consider for this child and additionally for any other subsequent pregnancies?

You are trying to find a blood donor to help treat some of your patients. The C-yonce and Kay-Z have 3 children with blood types A , B, and O. The youngest with blood type O needs a transfusion and you're trying to figure out if either of the parents are a match so you test the parent genotypes. Note: Alleles for each blood type are expressed as follows: blood type A= I^A blood type B= I^B blood type O= i Hint: Remember that 2 alleles contribute to a persons blood type. Pay attention to dominant and recessive relationships among the alleles.     1-C-yonce is type B. What must her genotype be? 2-What must Kay-Z’s genotype be? 3-Which parent can give blood to their child ? 4-After running lab tests, it was discovered that the children's blood types were reported incorrectly.(This does not affect the genotypes entered for C-yonce and Kay-Z in the previous questions.) Their youngest actually has blood type AB, and still needs a blood transfusion.  Which parent can donate blood to the child…
