Each person has their own DNA profile, unless they are identical twins, in which case they would have the same profile, but unique fingerprints. Forensic scientists can use the DNA profile of a suspect and compare it to a profile that they found at the crime scene. Any DNA profiles that are on record, the same way fingerprints can be on record, is kept in CODIS (Combined DNA Index System). This is one way of positively identifying a person.

All of Korea would have been communist and much of what you see today with North Korea would probably have been the state of all Korea had the North won.

It also would have spread communism to a much farther degree and the U.S. would not have South Korea as an ally.
