So im trying to figure out if you can breed a super rusty eastern rat snake to a leucistic rat snake if itll produce visuals or just hets. Im new to rat snake breeding so what research ive done is very confusing and at this point im lost. Help would be appreciated in understanding the difference.

I would need to double check myself as rat snakes are not my thing, but if I recall correctly a SuperRusty is a Leucistic… So I am not quite sure I understand why you are differentiating between the two of them in a theoretical breeding as if they were different. Am I missing something in your question???

I will add here that I am in the same boat as you, Travis… to my knowledge, super rusty was a Lucy combo
Well when i do genetic calculator or ask google it says they are different genetics. Says the offspring would be rusty het leucistic if i do a super rusty to a leucistic.
This is because any Super variant of a morph will create offspring that all have the single gene version of the super.
For example, not in Ratsnakes but in Ball Pythons (the genetic thing still applies tho) :
If you pair a Super Lesser (Blue Eye Leucistic) to say a Normal, you’d get all Lessers.
I believe the reason why its saying “het Leucistic” is because you have a gene that when doubled, creates a Leucistic.
I’m not too versed in Ratsnakes so I’m not sure what genes would contribute to making the “Leucistic” in your pairing calculator a Leucistic but I’m just sharing my knowledge of what may be going on here.

OK, I just did some reading. Super rusty is Lucy. So if you’re gonna breed a Lucy to a rusty You were going to get 50% Lucy and 50% rusty.
Or if we take your example, a rusty breeding to a Lucy would create all Lucys.
Ok thanks for the help everyone.

I am tapping in to a few of my friends that know a bit more about rat snakes than I do to see if I can get clarity

Okay…
I talked to some people and did some history digging
There are two or three different leucistic morphs among rat snakes as a whole: SuperRusty and TX Leucistic are valid and verifiable. Apparently there was also once a unique black rat Leucistic but no one can verify if that mutation is still in the hobby or has been lost
The SuperRusty Leucistic is an incomplete-dominant mutation. The TX and black rat Leucistics are/were both recessive
Complicating this, is the fact that the visual Lucy forms of both SuperRusty and TX are indistinguishable from one another so there have been cases where “visual” x “visual” have been bred together thinking they were the same thing only to end up with “Rusty Texans” that carry both mutations. And then, making it even worse, those “Rusty Texans” get backfolded into pure TX rats so you end up with ‘Rusty TX Lucies’
So… All that said, @jscott0292, based on the phrasing of your question, it seems like what you are getting in calculators is the “Rusty Texan” result - two different and incompatible forms of leucism, one inc-dom and one recessive. Which makes offspring that are essentially double hets, it is just that the Rusty is a visual het and the het TX is not
Make sense??

Read it like four or five times but yes now it makes sense lol
Yes makes sense I was hoping that one had blue eyes and the other black or something distinguishable to tell them apart. The research ive done pointed towards the info youve included but I was hopeful somebody with experience might could give some solid pointers to tell them apart. Thanks for the digging youve done to help out here. Hopefully this helps others that plan to get into the lucy genes.
