Heterosis, hybrid vigor, or outbreeding enhancement, is the improved or increased function of any biological quality in a hybrid offspring.The adjective derived from heterosis is heterotic.An offspring exhibits heterosis if its traits are enhanced as a result of mixing the genetic contributions of its parents.eterosis is often discussed as the opposite of inbreeding depression although differences in these two concepts can be seen in evolutionary considerations such as the role of genetic variation or the effects of genetic drift in small populations on these concepts.
