Hybridogenesis is an unusual form of reproduction that is found in hybrids between different species. It involves the selective transmission of one of the parental genomes, while the other one is renewed by mating with the corresponding species. It is seen as a form of sexual parasitism, in which the hybridogenetic genome gains a twofold transmission advantage and exploits the reproductive effort of another species.
