A Foreign Science; Forensics.

There are two main-streams of forensic science; genetics based forensics and physiology based forensics. Genetic based forensics determine the identity of suspects on the DNA material, whereas the physiology based forensic works on phenotype, i.e. works on the proteins of your body fluids, saliva, semen, dirty sweat or your finger prints of bodyl dirt. Although there are studies trying to link your finger prints to your genes, these are preliminary studies and are not to reliable yet. These studies might be or might be or might not be informative enough for identity determination. Future will show that.

So far DNA based identity determination is the most reliable approach.

Please be careful; "DNA information is not @ your finger tips, yet".
