It is possible for identical twins to have identical DNA, but very often that is not the case.
yes if the 2 people are identicle twins
It is very unlikely for two people to have the exact same DNA, except in the case of identical twins who share nearly identical genetic material. Even siblings from the same parents have unique combinations of DNA due to the random assortment of genetic material during reproduction.
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.
Variations in gene expression, environmental factors, and lifestyles can all contribute to differences in individuals with the same genome. Epigenetic modifications, such as DNA methylation and histone modification, can also play a role in gene expression. Additionally, random mutations can accumulate over time, leading to genetic diversity between individuals with the same genome.
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
Yes. Within a single person, all of the somatic cells have the same nuclear genomic DNA; it does not matter if you compare DNA from a cheek cell to a liver cell.
that no two people have the exact same DNA
No. They don't have the same DNA.
