In genetics, paternal mtDNA transmission and paternal mtDNA inheritance refer to the incidence of mitochondrial DNA (mtDNA) being passed from a father to his offspring. Paternal mtDNA inheritance is observed in a small proportion of species; in general, mtDNA is passed unchanged from a mother to her offspring,[1] making it an example of non-Mendelian inheritance. In contrast, mtDNA transmission from both parents occurs regularly in certain bivalves.

In animals

Paternal mtDNA inheritance in animals varies. For example, in Mytilidae mussels, paternal mtDNA "is transmitted through the sperm and establishes itself only in the male gonad."[2][3][4] In testing 172 sheep, "The Mitochondrial DNA from three lambs in two half-sib families were found to show paternal inheritance."[5] An instance of paternal leakage resulted in a study on chickens.[6] There has been evidences that paternal leakage is an integral part of mitochondrial inheritance of Drosophila simulans.[7]

Mitochondrial Inheritance Patterns

In human mitochondrial genetics, there is debate over whether or not paternal mtDNA transmission is possible. Many studies hold that paternal mtDNA is never transmitted to offspring.[8] This thought is central to mtDNA genealogical DNA testing and to the theory of mitochondrial Eve. The fact that mitochondrial DNA is maternally inherited enables researchers to trace maternal lineage far back in time. Y chromosomal DNA, paternally inherited, is used in an analogous way to trace the agnate lineage.

In protozoa

Some organisms, such as Cryptosporidium, have mitochondria with no DNA whatsoever.[23]

In plants

In plants, it has also been reported that mitochondria can occasionally be inherited from the father, e.g. in bananas. A recent study further demonstrated that paternal mitochondrial transmission also occurs in Nicotiana tabacum (tobacco), where paternal mitochondria are able to rescue plant growth and developmental defects caused by mutant mitochondria inherited from the mother[24]. Some Conifers also show paternal inheritance of mitochondria, such as the coast redwood, Sequoia sempervirens.[25]
