1. Riiiiight. Of course. I'm dumb sometimes.1. 25% : 75% is 1:3. 1 female for every 3 males (or out of every 4 Pokémon.
2. Oh; well in that case, no it is not possible to get a hex 0 Pokémon from hex 29 and hex 31 parents. Since (even without Destiny Knot) 3 IVs are passed from the parents, any offspring utilising those parents would have at least 3 IVs not at 0.
2. Ah crap, I meant test parents. Like using hex 0 and hex 29 test parents when testing for a hex flawless offspring, would using hex 31 and hex 29 test parents be fine for testing for a hex 0 offspring?
