must be identified. We know that the DNA of any human being on earth is not exactly the same. Yet most of the DNA of the mother , father and child match in the double helix. Therefore, the parents of the child can be identified. It cannot be 100% sure that any person is the parent of that child. However, it is impossible for people with similar DNA to live in the same place in the same country. So the person who claims to be the parent of the child can be identified only if the child's DNA matches most of their DNA.
