I think the question was if you could add more genes to a BEL and still see it.. It seems to dpend on HOW you make the bel. super mojave pastel is supposed to look different. And remember both potions are acualy a mix of 2 BEL genes.
Any BEL breed to a normal will make 0% normals. If it is a super form of 1 gene then all the offspring will be the non super version, if the bel is made with 2 genes it will be 50/50 mix of those genes.
