Hybrid sterility refers to the inability of a hybrid offspring to produce viable gametes, which leads to infertility. This particularly affects species that have different numbers of chromosomes, which can create problems during meiosis and result in non-viable gametes in the hybrid offspring. Therefore, hybrid sterility is a post-zygotic reproductive barrier that prevents the development of viable, fertile adults. The other options listed are pre-zygotic barriers that prevent the formation of a hybrid zygote in the first place.
