Final answer:
DNA fingerprint analyses can determine if a person's DNA matches DNA found at a crime scene, providing evidence of their presence at the crime scene.
Step-by-step explanation:
DNA fingerprint analyses can be used to determine if a person's DNA matches DNA found at a crime scene. By comparing the DNA profiles, scientists can identify if the person's genetic material was present at the scene.
If there is a match between the DNA from the suspect and the DNA from the crime scene, it provides strong evidence that the person was present at the scene of the crime.
