hybrid zone A zone that exists between the populations of two related species, whose geographical ranges overlap, which contain hybrids resulting from matings between the two species. The hybrids, which have a reduced fertility, will eventually act as a barrier between further interspecific mating and hence will restrict gene flow between the two species.
