Another morph/gene combo question

Ok so before I think about breeding and what list of animals I want to work on, I have another quick question about genes. So from reading the basics on genes here I want to make sure I understand this. If I take a dominant gene animal like a Pinstripe that is either het for pied or visual pied and breed it to my pied girl, I would come out with pinstripe pieds right? And if I took say a co dominant animal like a butter or enchi or fire or lesser which is het for pied or visual pied and bred that to my pied girl, I would get visual co domiant pied animals like enchi pieds or fire pieds etc? And the last thing, how come I cant find anything on butter pieds? I ask this because I was thinking if I got a lesser or butter het or visual pied male and then a butter or lesser female, I could make BELs with them and also breed the male to my pied girl and get co dominant visual pieds.

Basically. There's a little more math involved, because genetics is never as easy as this plus that gives me what I want.

When breeding a piebald female to a pinstripe het pied male, you have 25% odds all around for a normal het pied, a pinstripe het pied, a visual pied, and a pinstripe pied. If you bred a visual piebald female to a pinstripe piebald male, 50% of the babies should be regular piebald, 50% should be pinstripe piebald.

Codoms only really work differently when bred to the same gene or something in that complex. Otherwise the same rules apply as for dominant traits. A piebald female to a het or visual piebald male with any codominant trait will give you the same odds as above, except replace pin with whatever gene of your choice.

It may be possible that someone just hasn't bred a butter pied yet. I don't imagine there being a ton of interest in piebalds involving the leucistic complex, just because breeding them back together produces a totally white snake that may be piebald, but won't look it. Genetically I can see a piebald leucistic having some value, but visually it's a pretty pointless combination. A piebald with no piebalding is hardly worth it, you know?

The butter pied has been produced, it is a 100% white snake, like the lesser pieds typically are. They are both really nice, if you like white snakes. They are pure white, no spots, speckles, tints, or anything else, just white.

Here is one of the lesser pieds that I produced 2 years ago. The lighting wasn't great, so she looks like she has a pink tint to her, but she is really pure white.
