Hybrid inviability

Hybrid inviability is a biological barrier to successful reproduction between different species or populations. When two species mate, their combined genes may produce offspring that cannot develop properly or survive to adulthood. This happens because the genetic differences interfere with vital biological processes. Essentially, the hybrid embryo or fetus fails to develop normally or dies early, preventing the hybrid from reaching reproductive age. Hybrid inviability helps maintain distinct species by reducing interbreeding when offspring are unlikely to survive or be fertile.
