A retrospective analysis of the theoretical developments of the causes of the phenomenon of heterosis has been carried out. In connection with new scientific achievements of the fundamental sciences, various hypotheses of heterosis have been revised. A new hypothesis has been proposed, according to which heterosis is explained by the relationship between genetic heterozygosity and the high initial potential of free energy of germ cells, caused by increased work and reproduction of mitochondria. This work of mitochondria is regulated by the hypothalamus in response to signaling by free radicals and humanin of the conditions of interaction between the nuclear and mitochondrial DNA of parental individuals of different breeds (cultivars) caused by environmental factors, for example, stress, a certain force within the limits of the species reaction. As a result of incomplete interaction between nDNA and mtDNA of different breeds, a sharp increase in the work of mitochondria occurs, enriching the hybrid with energy, which is accepted as hybrid strength or heterosis. Various ways of improving the work of mitochondria are considered, which can enhance heterosis and, at the same time, increase the productivity of animals and plants.
