Lethal gene in breeding Champagnes?

Just saw an ad for someone selling a mojave champagne female and a champagne male b.p. Poster is suggesting buyer could breed the two for super champagnes. I'm sure I've read somewhere that breeding champagne to champagne carries the risk of a lethal gene and hatchlings dying in the egg or shortly after hatching.
I have no interest in purchasing either of the snakes listed for sale but was interested in the claim made by the poster because i do have a champagne b.p.. Can anyone comment on the possibility of a "lethal gene" factor in breeding champagne to champagne.

Some people are unaware of the lethality. I didn't know about it until after I had a champagne. So maybe the seller is unaware, or a more shady likelyhood they are hoping the buyer won't be aware.

Super Champagne is indeed lethal so are a few other combinations, see this http://www.owalreptiles.com/issues.php for details.

Many people are not that knowledgeable when it comes to genetics let alone with potential issues when it comes to specific mutations. And some people will say ANYTHING to make a sale, years ago someone wanted to trade me 1.2 desert for some enchis and they told me their desert would lay eggs. (it was early but already known they would not)

Please educate me, why would the desert not lay eggs, another genetic malfunction?

There are different theories usually female Desert end up egg bound and know has been known to lay a viable clutch here is a good article from my friend Justin who documented his journey https://jkrballstreetjournal.com/201...nd-case-study/ here is another friend's personal experience http://www.albeysreptiles.com/desert07_1.htm#desert and there are many others.

Since the project has pretty much been abandoned while Desert make cool combos basically females are pet only.

Yup genetic malfunction. They'll ovulate mate and go gravid but can't lay them. Surgical intervention is always required.
