The jmgs came from a lemon ghost pairing breeding for yellow hogs. They popped up in the offspring and were proved codom. The difference between codom and polygenic is that u can breed the codom and get a desired result in two generations as with the super form. But with polygenic or line breed traits to get to something that looks like that super jmg would take a crazy amount of generations. It would I think take a lifetime instead of a codom or resessive trait.
