PROBLEMS (Answer in your notes)

John has blood type AB and Jenny has type O. Draw the cross and Punnett square and list the possible blood

types of their offspring.

Mary has blood type A (I

) and Marvin has blood type AB. Is it possible for them to produce baby Melvin

with blood type A? Draw the cross and Punnett square and explain.

Samantha has blood type B and Simon has blood type O. Use the dash technique to draw the cross and

Punnett square and explain if they can produce a type O child.

Paul has blood type A and Peter has blood type AB. Penny has blood type B and baby Peewee has blood type

O. Both Paul and Peter believe they are the father. Using crosses and Punnett squares and explanations,

determine if one of them is more likely to be the father. Is this individual DEFINITELY the father? How could

you tell for sure?

If Penny needed a blood transfusion, could either Paul or Peter donate blood to her? Explain using relevant
