In most cases, sibling tests are performed to determine paternity—whether or not the two individuals have the same biological father.

Why are sibling DNA tests different?

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.
