Suppose two suspects in a crime have DNA profiles that match the one DNA fragment tested. What should happen next?
A)Both suspects must be guilty and should be charged with the crime.
B)The test should be repeated because a mistake must have occurred.
C)A different hair or blood sample taken from the crime scene should be analyzed for the same DNA fragment.
D)The sample taken from the crime scene should be analyzed for multiple DNA fragments.

4. Suppose that the DNA pattern generated from the hair sample at the crime scene did not match any of the DNA patterns of the suspects. Which conclusion can be drawn?
A)Only one of the suspects can be ruled out.
B)None of the suspects can be ruled out.
C)All of the suspects can be ruled out.
D)A mistake must have been made and the test will have to be run again.

The first one is D, because the probability of multiple suspects to share one fragment that is tested is much higher than when multiple fragments are tested. The FBI uses 13 when running crime scene tests.

The second one is C, if multiple patterns are used in testing and neither suspect share ANY of them then it is generally safe to exclude them from the investigation.
