The ABO Blood Group is the most popular of the many others that are known. At one time, forensic blood samples were used to distinguish between individuals using the ABO system. However, this did not work. Why? :?

well, because two individuals can have the same blood type and not be related at all. if you have blood and need to do forensic research, you isolate the white blood cells, then isolate the DNA, amplify it by PCR and presto, RFLP test possible with a 99% reliability. (i have done it myself actually. it's much easier than it sounds)
