What gene is making this snake white?

I've got a super blade clown male and a super enchi, butter, OD, pastel, 100% het clown female.

I was looking at possible offspring combos, and I really like the way the Pastel Enchi Butter Blade Clown looks.

What is causing the white to come through in this snake? None of the other combos I've seen have white.

You pretty much answered your own question I think. The name is on the tin and if you look up previously sold snakes by Wilbanks with that set of genes, you will find very similar snakes.

Some of it is definitely line bred, so you may not see as much white depending on how each parent appears, but you should have the possibility of creating a similar snake with the pair you have.
Every snake will be enchi blade. From there it's a toss of the coin to see what else.

I should also elaborate a bit that it isn't quite which gene that's causing the white, it's the whole package that causes that white.
If you remove any of those listed genes, the animal can look amazingly different. The pastel on top of the enchi butter/lesser blade clown will definitely add more white, but you won't get that end look without all 5 genes at play. Without the pastel you will still end up with a yellow snake with some white a little further up the sides.

Lesser will reduce the black to brown and start bringing in the white sides.
Clown changes the pattern
Enchi brings in a cleaning effect of sorts, brightening the yellows and enhancing the dorsal pattern.
Blades further reduces the side patterns and helps bring up more whites from the belly
Pastel further enhances the color and brings more white on the sides.

Thank you for the information, I really appreciate it.
