Quick question regarding breeding types.

[Hwona]

If I'm not wrong, heuristic breeding generates a baby adoptable with the same species as the mother or the father. If you breed a blue dog and a red dog, you'll get a blue dog OR a red dog.

Advanced breeding performs this same function along with another one: you can create special "baby" species that can be bred from certain combinations of parent species. If you breed a blue dog and a red dog, you'll get a blue dog or a red dog... or a purple dog.
