Yeah it could have 10 genes but if its ugly you get $10, but if one gene makes pretty you get 10 or more times that. When I was breeding corns I produced a butter stripe, which is actually a 3 recessive gene combo, so in some ways you could say you have to hit 6 copies of genes aka 6 banger. I was breeding triple het to triple het parents, so the odds of producing a butter stripe is 1/64, which is insainely difficult, but thank god corn snakes can lay two clutches of 15+ eggs for a total of 30+ eggs per year. Anyhoo, all that to make one and I think they were only worth $300 back then.
