Because of the … WebMultilocus interactions (also known as Dobzhansky-Muller incompatibilities) are thought to be the major source of hybrid inviability and sterility. Because cytoplasmic and nuclear genomes have conflicting evolutionary interests and are often highly coevolved, cytonuclear incompatibilities may be among the first to develop in incipient species.
