Jeffreys, Alec John. 1/9/1950 â ENGLISH GENETICIST. Alec John Jeffreys is a geneticist who is best known for the introduction of DNA analysis to forensic science. He discovered one of the most important tools for identifying human beings, genetic fingerprinting. This procedure analyzes each individual's genetic code.
1 DNA fingerprinting was invented in 1984 by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites.  DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual.
