An example of a postzygotic mating barrier, low hybrid viability .
Hybrid offspring are born but have lower fitness and are therefore less likely to reach sexual maturity. Another example is where hybrid offspring is healthy but unable to breed.
Postzygotic mating barriers reduce the reproductive capacity of hybrid offspring. The three types of postzygotic barriers are hybrid zygote abnormality, hybrid infertility, and low hybrid viability . Many research theory suggests that incompatibility alleles those who have evolved neutrally are not able to be maintained in secondary contact.
