When are incubator contents determined


so does anyone know when the contents of an incubator is determined?

I know in PoGo it was discovered that the content of an egg were determined when the egg was obtained, not when it hatched.

i have a feeling JWA incubators are the same but does anyone know?


I’m pretty sure there’s a trigger like DNA fusions, but I doubt anyone has it figured out. I have observed getting specific DNA in waves (Velo, Trike Gen II, Stego, etc.) though.
