The consequence is that the sample becomes degraded and therefore unusable for paternity testing..

Can siblings have different DNA?

Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That’s true even for fraternal twins.

What does a DNA test say when you are not the father?
