Question 2: Case 2 A young woman who was adopted at birth, comes into your office asking you to help her identify her birth father. She
already knows that the blood type of her birth mother is A positive. She knows her birth father is one of three men who are
willing to help in her search. Your first step is to do a blood test on the daughter. Your results show that she is type AB
negative. You make some phone calls and have the three possible fathers come in to give a blood sample. Here are the
results:
• Man #1 - O negative
• Man #2 - B negative
• Man #3 - AB positive
From this information, can you conclude who the father is? Is there anyone you can exclude? What tests could you do further
to confirm your analysis about who the father is?
