Every time I hatch, I get the same pet, with the same Pedigree, and the same exact stats. I don't know if it's a glitch or what? But I'm getting tired of wasting 50,000 each time for the same thing every time.
It all depends what you hatch with. If you keep hatching the same pet with the same pet, you will keep getting the same pet. If you hatch 2 of the same 1st generation pet, you will ALWAYS get the same pedigree and stats because there's no differences in the parents.
