Homoplasmy

From Biocrawler, the free encyclopedia.

Homoplasmy is the presence of a mutation affecting all of the mitochondrial DNA (mtDNA) copies in a cell. Since there are hundreds or even thousands of mtDNA copies in every eukaryotic cell, mutations may either be present in all copies, homoplasmy, or affect only a fraction of them (heteroplasmy).

See also microheteroplasmy.
