Post-zygotic Barriers

Hybrid inviability: hybrid fails to develop or fails to reach sexual maturity

Behavioral sterility: hybrid reaches sexual maturity but fails to produce appropriate courtship displays or mating behavior (plants may grow flowers that fail to attract pollinators)

Hybrid sterility: hybrids fail to produce functional gametes
