DNA fingerprint, the method
individual identification using DNA,
based on the fact the DNA of every
(with exception of identical
and individual clones) contains
sequences exclusive to each
.

Although normal individuals of same
species have the genes in their
chromosomes, individual has
different alleles even in the inactive
