Imagine that you are a detective who has identified a potential suspect in a homicide. You acquire a small amount of blood from the crime scene and hand it over to your lab. The lab carries out PCR for one polymorphism, and it returns as a match to your suspect. Is this enough to arrest your suspect?
A. Yes, these data definitively prove that your suspect was at the crime scene.
B. Yes, the chance that your suspect will have the same polymorphism as a drop of blood from a random individual is about 1 in 50,000?this is enough to arrest the suspect.
C. No, your lab should assess additional polymorphisms?a single polymorphism does not constitute a genetic fingerprint.
D. No, the small amount of blood you acquired from the crime scene will not provide enough genetic material for PCR to be carried out efficiently?more than a single drop of blood is needed to provide enough raw material for analysis.
Answer: C. No, your lab should assess additional polymorphisms?a single polymorphism does not constitute a genetic fingerprint.
