DNA fingerprinting relies on the presence of simple tandem-repetitive sequences that are present throughout the genome. The regions show length polymorphisms, but share common sequences. DNA from different individuals is cut and separated by size on a gel. A probe containing the core sequence is used to label those fragments that contain the complementary DNA sequences. The pattern of each gel is specific for a given individual, and can be used to establish parentage.
