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.
Siblings who share only one parent have approximately one quarter of their DNA in common. However, DNA does not always copy perfectly, and small errors are common. Small mutations and recombination errors ensure that even twins won't share exactly the same DNA.
