Pewter &/or Okeetee pairing question

I recently acquired 4 adult snakes: male Pewter, female Motley/Miami, female Snow, female RedFactor; and I also have an adult male Okeetee. I plan to get onto MorphMarket's genetic calculator this weekend, but in the meantime any pairing suggestions? Thanks!

So, most corn snake gene mutations are recessive, meaning you need to have two copies of the gene to visually express it. Your snakes may be carrying hets (and probably are!), but without knowing what they are, none of your snakes match up genetically. The okeetee is a line bred look, as well as the Miami. Red factor is incomplete dominant, so that one can potentially pass on the gene in the first generation of babies. Personally, I would look at what morph combos you like that include the genes you know your snakes have, and pick a new snake based on where you want your project to go. Or, if you don't want to add any new snakes, I would breed the pewter to the snow, since those are both two gene morphs (diffused plus charcoal and amel plus anery) to cast the widest net as far as discovering any hidden hets. They may end up sharing no hets at all and you would yield all normals from that pairing.

Thanks for the reply.

According to the MM calculator:

pewter x red factor = corals for 50% of the offspring
Okeetee x red factor = okeetees for 50% and coral okeetees for 50

Every other pairing results in all normals.

Sounds like it's not even worth breeding them. I'd wind up giving the babies away for free.

I saw an ad on Fauna last week, guy looking for all the normal hatchlings he can find. I wonder if he has king snakes to feed. I know Ball python hatchling normals are often fed to kings. What a shame, what a waste.

How did people figure out all these percentages before morphmarket?

Punnett squares have been around for a very long time! But also, iansvivarium.com has a nice calculator too. Figuring out the inheritance pattern of new genes has always taken test breeding though. But once it's known whether they're recessive or dominant, then you can use a Punnett square to figure out potential offspring.

And since okeetee is a line bred look, that calculation isn't exactly correct. You'd certainly have a chance to pass on the okeetee look to some of the babies, but if you're not breeding it to another okeetee, it's unlikely any of the babies would look as strongly okeetee as the parent.

I've tortured many s student with Punnett squares over the years, lol. I love the convenience of the online calculators for multi-trait crosses, but I am old school enough to feel like a solid handle on basic genetics is very helpful in understanding results. If nothing else, it let's me know when I mistyped an entry. Lol

I saw that ad on fauna for normal corn hatchlings. I also wondered if they wanted them as prey.

Not necessarily. I do agree that the ones you currently have wouldn't match well with one another. That doesn't mean you might not decide to find another animal whose traits match one you've got. As Olivia said, take your time and look at pics of a lot of different snakes as adults. Maybe you'll decide you love pewters, or hypo pewters. That's an easy cross for you. Maybe you really like Oketees, and want to produce them. They're consistently popular.

Do take your time. Think seriously about what you'd like to be producing, and what you need to get there. And yes, think about what you would do with the babies you didn't plan to keep. That's just being reasonable and responsible. Your earlier comments show that you are both. I wish you luck in figuring out whether you'd like to breed, and if so, what.
