WebThe mtDNA test traces a person’s matrilineal or mother-line ancestry using the DNA in their mitochondria. Unlike the Y-DNA, which is only passed from father to son and not to daughters, the mtDNA is passed from the mother to all her children, including males and females. This means that people of either sex can take the test. Web8 aug. 2012 · Mitochondrial DNA (mtDNA) analysis allows forensic laboratories to develop DNA profiles from evidence that may not be suitable for RFLP or STR analysis. While RFLP and PCR techniques analyze DNA extracted from the nucleus of a cell, mtDNA technology analyzes DNA found in a different part of the cell, the mitochondrion.
