hmm where did you get these snakes?? if it was from a breeder, did they tell you they were het pied?? The percentages are the percent chance that your snake IS het pied (het means carries the gene). So basically your snakes are either het or they are not. This is what serpent merchant is getting at....Assuming that BOTH of your snakes are in fact het for pied then they have a 25% chance of producing a pied baby
