In these cases, the zygote formed is called a hybrid. However, even after a hybrid zygote forms, reproduction may still not be successful. When that reproduction ...

en.wikipedia.org/wiki/Hybrid_inviability
The barrier of hybrid inviability occurs after mating species overcome pre-zygotic barriers (behavioral, mechanical, etc.) to produce a zygote. The barrier ...
