The big advantage in this method is that the DNA comparisons can match the possibilities into an almost endless range. DNA fingerprinting has been extremely successful for use in the personal identification of criminal suspects, DNA testing for ethnicity, identification of the deceased, as well as court-approved paternity tests. read more

DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual. This is a DNA fingerprint. read more
In its short history, DNA fingerprinting has undergone greater scrutiny than any other method of criminal investigation, including ballistics, handwriting, lie detection, eyewitnesses and fingerprinting. The Drawbacks of DNA Fingerprinting. There are some problems with DNA fingerprinting though: Expense. Some DNA tests are relatively inexpensive. read more
