Answer:
No, it's practically impossible.
Step-by-step explanation:
Its because everyone has two copies of most of their genes, sometimes differing from each other. Parents pass down one of their two copies of each gene to their kids; these copies being totally random. One human has between 20,000 and 25,000 genes, so its extremely rare for two children to have the exact same genes as each other, even if their identical twins. Side note: Identical twins may have the same DNA, but they don't have the same genes since sometimes one twin may have more freckles than the other or etc.
