DNA fingerprinting (also often called "DNA profiling") is a powerful tool that allows the unique pattern of certain common polymorphisms within an individual's genome to generate a unique genetic profile.  It is most famously used in law enforcement in cases where criminals leave DNA evidence at the crime scene.  More commonly, DNA fingerprinting is also used to determine genetic relationships between individuals; this application is widely used in research and paternity testing.

Recent advances in genomics and molecular biology have allowed for several different DNA profiling techniques to be developed.  As with any set of tools, each technique has its own advantages and limitations; the best technique to use most often depends on the application or, especially in criminal cases, the situation.
