It is possible for identical twins to have identical DNA, but very often that is not the case.
No
No two people have the same genome - everybody's DNA is slightly different.
yes if the 2 people are identicle twins
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. If the current population of the earth was your sister, it is unlikely another person would have DNA close enough to yours they could be mistaken for your identical twin. The odds of two unrelated people sharing the same DNA is substantially smaller yet.
It depends... if you mix your DNA with a giraffe, it could be possible.
It is not possible because they are not in the same family. Can only mix DNA in ones family.
NO
I think this is related... No two people on earth can have the same DNA (genetics) so they wont be the same although they will be simalar though it is possiable to distinguish brother from sister, mother from daughter etc.
With the same last name it's possible, but you could be related to people who don't share a last name with you. I guess the only way to truly know is through DNA testing.
Maybe, I mean they could evolve to become these pigs with wings, so anything's possible. Or, they could not evolve and have avian DNA put into their DNA, it could happen. But we don't know for sure if they will, but anything's possible
No, but their DNA is closer to each other than other people.
that no two people have the exact same DNA
No. They don't have the same DNA.
