3. At 1.00 a.m., someone breaks a window in the back of a store and robs the safe. On the way out, the thief cuts himself (or herself) on a piece of broken glass. You are a forensic detective called to the scene,. You test a sample of blood left behind by the thief. It is O-. While you are there, police bring in a suspect with a cut forearm who was arrested just three blocks form the store. You take a sample of the suspect’s blood and mix it with anti-A. You immediately know that the suspect is not the person who cut himself on the broken glass in the stores. How do you know this?

4. Suppose the above suspect’s blood does not agglutinate when tested with anti-A or anti-B, but does agglutinate when tested with anti-Rh. Would this connect the suspect with the crime scene? Explain your answer.
