How many people have been found with the same DNA?

The concept of DNA is based on the uniqueness of genetic material for individuals, making option none the best answer. While identical twins share the same DNA, it is generally accepted that no two individuals, outside of identical twins, have identical DNA profiles. This uniqueness is crucial for forensic science, as it allows investigators to match biological evidence to a specific person with a high degree of certainty. In criminal investigations, DNA profiling is a powerful tool because it can link a suspect to a crime scene or eliminate individuals from suspicion based on distinguishing genetic markers. Therefore, the focus on "none" indicates a fundamental understanding of the genetic principles that guide DNA evidence in legal contexts.
