Discovery, Development, and Current Applications of Dna Identity Testing

Genetic identity testing involves identifying the patterns of genetic material that are unique to almost every individual. Although over 99% of the DNA sequences in the human genome are identical between individuals, a small number of sequence differences are used to distinguish all humans (1). Those different sequences are usually targeted for identity testing. The techniques that are applied in identity testing are DNA fingerprinting, DNA profiling, and DNA typing. Although there are some technical differences between these tests, the terms have been used interchangeably.
