On
4、ly in the last decade or two, however, have scientists begun to believe that genetic markers in blood and other bodily fluids may someday prove as useful in crime detection as fingerprints.The standard ABO blood typing has long been used as a form of negative identification. Added sophistication cam
5、e with the discovery of additional subgroups of genetic markers in blood and with the discovery that genetic markers are present not only in blood but also in other bodily fluids, such as perspiration and saliva（口水）.These discoveries were of little use in crime detection, however, because of the cir
6、cumstances in which police scientists must work. Rather than a plentiful sample of blood freshly drawn from a patient, the crime laboratory is likely to receive only a tiny fleck of dried blood of unknown age from an unknown “donor” on a shirt or a scrap of rag that has spent hours or days exposed t
7、o air, high temperature, and other contaminants.British scientists found a method for identifying genetic markers more precisely in small samples. In this process, called electrophoresis, a sample is placed on a tray containing a gel through which an electrical current is then passed. D.A trained an
8、alyst reads the resulting patterns in the gel to determine the presence of various chemical markers.Electrophoresis made it possible to identify several thousand subgroups of blood types rather than the twelve known before. However, the equipment and special training required were expensive. In addi
9、tion, the process could lead to the destruction of evidence. For example, repeated tests of a blood-flecked shirt-one for each marker-led to increasing deterioration of the evidence and the cost of a week or more of laboratory time.It remained for another British researcher, Brian Wrexall, to demons
