Well unless one of the parents is holding an everstone, the offspring will not be the same nature. But as for the IVs[characteristics], 3 of the 6 IVs will be randomly taken from the parents, and the other 3 are completely random. Here's a hypothetical situation, lets say you are breeding two Galvantula and the IVs are as noted [female(Modest); 31/31/31/31/31/31: male(timid); 31/31/31/31/31/31] I said hypothetical. So if the male holds the everstone, you have a high cahnce of the offspring being a Timid nature. So now you put them in, and you are guarenteed at least 3 IVs to be at 31. So now lets say you want 31 SpA IVs, you would give the Female the Power Lens[for SpA] and put them in. YOu would probably get a Joltik similar to this (X=whatever IV because you cannot calculate them all) [ Joltik (Timid); X/X/X/31/X/X] But remember, at least two of those X's would also be 31 IVs becaue both parents had 6x31 IVs. If this is too complicated to understand, jsut let me know ;)
