Michaelis firmly believed in complex unity in the cytoplasm, but he rejected simplistic notions such as the plasma gene or that the cause of cytoplasmic inheritance was solely due to plastids and mitochondria. His work contributed largely to the development and understanding of organelle inheritance

divisions. He suggested two possible ways the plastid could influence one another: (1) The mutant plastid might manufacture a substance that damaged the normal plastids during the maturation process. (2) The normal plastid might manufacture a substance that would allow the mutant form to develop

Theory predicted that the two types could be distinguished clearly by an examination of the distribution of mutant and normal cells. Michaelis found clear examples of both types of mutation in his material and published his work in 1956.
