Imagine that you are a detective who has identified a 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, a match between dna fingerprints is always definitive proof that the two sources are the same individual.
b: yes, the chance that your suspect will have the same polymorphism at a single site 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 dna 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.
