WebMitochondrial DNA (mtDNA) is the physical embodiment of the genetic information encoded in the mitochondrion. Technically, the term ‘mitochondrial DNA’ encompasses not only the mitochondrial genome per se, but additional DNA types (e.g., small linear plasmid-like DNAs) that are present in the mitochondria of some organisms.

In most multicellular organisms, mtDNA is inherited from the mother (maternally inherited). Mechanisms for this include simple dilution (an egg contains on average 200,000 mtDNA molecules, whereas a healthy human sperm has been reported to contain on average 5 molecules), degradation of sperm mtDNA in the male genital tract and in the fertilized egg; and, at least in a few organisms, failure of sperm mtDNA to enter the egg.
