DNA Identification Evidence Law and Legal Definition

DNA identification is based on the universally accepted principle that two people will not share the same genetic configuration. Therefore, by examining the sizes of enough fragments at different sites on different chromosomes, statistical procedures based on known sequence frequencies in the population can be employed to establish the uniqueness of any one person's DNA pattern.

Generally, DNA identification evidence, expressly or impliedly including statistical calculations of band pattern frequency in the population is admissible to determine identification.
