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.
A brother to sister (sibling to sibling DNA Test) works by testing a very large number of different DNA points (known as loci) in each person. Full siblings share a lot more DNA in common than do unrelated persons, and also, half siblings share more DNA in common than unrelated persons, but not as much as full siblings. So this test looks at the amount of DNA sharing and uses DNA statistics to evaluate the amount of DNA sharing to deduce biological relationship.
