Shedinja is an interesting pokemon in many ways. It's genderless so it will only breed with ditto AFAIK. The offspring will always be nincada. The gender of the offspring will not be affected by any factors whatsoever besides the natural gender ratio all duo gendered mons observe. The nincada should be in the regular Bug egg group and thus won't be able to breed with pokemon in the mineral egg group. Shedinja shouldn't be able to breed with ninjask or nincada.
I have not tested any of this. It's just my guess on what SHOULD happen based on experience.
