MMMM according to Kevin HG Woma is one mutation it was a Woma-ish snake that he improted that has since been proven to not be related to the regular woma gene. he was simply calling it a Hidden gene till he figured it out and the name stuck.. and and to my knowledge HG Lesser is one mutation since you can't just get a Hidden Gene animal it is tied to that stand of lesser .. So it's two mutation's not four. The Hidden gene thing confuses allot of people. I could see the 2.0 being like a pastel Lesser HG Woma or something..
Of course I've been wrong before.
