Having all copies of mtDNA the same within a cell or organism (compare heteroplasmy).Not to be confused with homoplasy, which means something entirely different

A cellular condition in which all copies of an organelle are genetically identical. See heteroplasmy.

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).

Resemblance between different plants or animals, in external shape, in general habit, or in organs, which is not due to descent from a common ancestor, but to similar surrounding circumstances.

The mitochondria of an individual consisting of a single population.
