WebBacteria that cause cytoplasmic incompatibility (CI) are among the most common maternally transmitted parasites of insects. In CI, uninfected females produce few or no offspring when they mate with infected males and, as a result, are often at a reproductive disadvantage relative to infected females. WebIn cytoplasmic incompatibility (CI) 6, matings between symbiont-infected males and uninfected females result in death of offspring at the embryonic stage.
