Most paternity tests are based on comparisons of DNA. DNA evidence can only exclude suspects. DNA sequencing is used because there are so many different sequences you could have at any one place, the odds of any 2 people, except identical twins, having the same DNA is nearly impossible. However, if people are very closely related (like father-son), they will share a number of common sequences on a DNA test. We'll say 5 out of 10. Though it's usually VERY unlikely, 2 completely unrelated people can still share sequences in certain places. This is why it can only legally disprove paternity cases. If 2 people shared no sequences, they couldn't be related. That's not to say, however, that 2 people who share a number of similarities are related.
