Illustration of shifts in heteroplasmy (HP) levels. Levels of HP can change during development. Especially for hairs, random assorting of mitochondrial genomes can lead to large shifts in HP levels. Once the HP level in the buccal cells is below the detection threshold of the analysis method, this may lead to an (apparent) homoplasmic mismatch with hair 2.
