Correct. DNA evidence is now well established in criminal courts. DNA analysis of any fetus would qualify it in a court as a different person than the woman carrying it. So the determinants about what make it a separate person under the law are time and position. If the baby's head clears the vaginal walls, it becomes a person. Could we therefore pass a law that says that people are only people when they are on the first floor of their house but not the second? Could we also say that we can legally kill someone before noon, but not after?
See what I mean Vern!
