Description
A mitochondrial DNA test (mtDNA test) traces a person’s matrilineal or mother-line ancestry using the DNA in his or her mitochondria. mtDNA is passed down by the mother unchanged, to all her children, both male and female. A mitochondrial DNA test, can therefore be taken by both men and women. If a perfect match is found to another person’s mtDNA test results, one may find a common ancestor in the other relative’s.
