If you were to breed Tauros with Ditto or something, would the egg always hatch into a Tauros or could it be a Miltank. I heard somewhere that a Miltank was just a female Tauros and was wondering if this is possible.
Tauros + Ditto= Tauros
Milktank+Ditto=Milktank
Milktank + Tauros= A Milktank- Since you cannot get a female Tauros

it will hatch only Tauros, same goes for Miltank+Ditto.
