The only way to have the same DNA of another person is if you and that other person came from the same sperm-egg combination (identical twins, triplets, etc, clones). They are still different though, but are good for organ transplants if you need one. Because your parents only pass on one allele for a specific trait.
Not even identical twins have the same DNA--although theirs would be far closer than anyone else's. DNA changes over time. Odds of two siblings having the same DNA who did not split from the same zygote are vanishingly small.
