Abstract
THE basis of cytoplasmic inheritance in the killer system of Paramecium aurelia has been located to endosymbionts* in the cytoplasm. Breeding experiments have shown the maintenance and replication of some of the endosymbionts in their cellular environment to depend on nuclear genes of the Paramecium host cell1. There are indications of a specific adaptation between the endosymbionts and certain strains or syngens (≡sibling species)2.
