^^ Not true.
Most horses are not JUST tobiano. Most have SOME overo (even if it's just sabino). So if a "tobiano" was bred to an "overo" you still COULD get one that is H/Z for tobi and/or some form of overo, IF the parents weren't "just tobi" or "just overo." I say that because horses will be registered tobi, overo, or tovero, but realy the majority are likely "toveros" and just not registered as such. Being just "overo" is more likely than just "tobi."
A "tovero" horse is NOT H/Z just because it has tobi and overo. You ABSOLUTELY CAN get solid offspring from them. The "tovero" MAY pass on Tobi, MAY pass on overo, MAY pass on both, or MAY pass on neither.
