I want to know the answer to the following question:
Fertilization happens where?
All the background I'm provided with is that "Some insects, like parasitic wasps, show polyembryony, where a single fertilized egg divides into many and in some cases thousands of separate embryos.:136–137 Insects may be univoltine, bivoltine or multivoltine, i.e. they may have one, two or many broods (generations) in a year.". Is that enough to answer the question?
Answer: no
