Hybrid sterility refers to hybrid offspring being unable to produce viable or fertile offspring. This means that even if a hybrid zygote were to develop into an adult, it would not be able to produce viable offspring and would therefore be a reproductive dead-end. The other options (gametic hybridization, behavioural isolation, and mechanical isolation) refer to barriers that occur before or during fertilization and would prevent the formation of a viable hybrid zygote in the first place.
