Despite the trend of people proving out their leopards to be het pied and still I have yet to hear of someone proving one not to be het pied. Looks like a lot of people got lucky. http://forums.kingsnake.com/view.php?id=2017839,2017839
In 2013 we bred a Spider Piebald (from a Leopard x Spider Leopard breeding theorizing that is was a Super Leopard) to 3 females for a total of 23 eggs. None of the offspring were Leopard. We are now convinced that the Leopard gene and the Piebald gene can be separated.

To further support our theory we have been made aware of 2 other Super Leopards that were not Piebalds. One of which is owned by Markus Jayne and was proven after producing 5 clutches with 100% of the offspring displaying the Leopard trait.
Looks like it is just another dominant trait. Kinda interesting how that pied gene stuck along those leopards for so long. Also he brought up the value of them at the end of the post. I wonder do you think Leopard het pieds will increase in value or just the regular leopards will decrease with this new info? Leopard no doubt does some pretty cool things regardless.
