The mtDNA
maternal lineage test is used to determine whether
two or more individuals are related through their
mothers (through the maternal/female line). This
test is often used to provide additional evidence in
difficult maternity cases where the alleged mother
is not available for testing. Results of this
testing may also be used to confirm the biological
relatives of an adoptee.
Mitochondrial DNA (mtDNA) is inherited through the
maternal line—that is, all sons and daughters
inherit their mother’s mtDNA. However, only
daughters can pass on their mother’s mtDNA to their
offspring.

Mitochondrial DNA is composed of a string of
DNA molecules in a particular order, or
sequence. In the mtDNA test, a short segment
of the mtDNA is sequenced (the order of DNA
molecules is determined) and the mtDNA
sequences from each individual are compared
to see if they could come from the same
maternal line. Everyone from the same
maternal line will have similar mtDNA
sequences.
