By 2020, however, there will be a significant change that will make DNA fingerprinting obsolete. The handful of markers used in DNA fingerprinting will give way to the infinitely more sophisticated personalized DNA sequences. Fingerprints may give us a match, but DNA may tell us what the person looked like and give us his or her medical history.

For example, by examining a single cell from a person’s dandruff, it is in principle possible (using the polymerase chain reaction process) to reconstruct the entire genome of an individual. Possessing the personalized DNA sequence, one can reconstruct important details of the person, including blood type, eye and hair color, sex, genetic diseases, general body shape, medical status, disposition to baldness, approximate height and weight, even body chemistry.

–Visions, Michio Kaku
