First off let me say that I'm new to breeding snakes, so please bear with my stupidity. I'm confident that I have a firm grasp on the husbandry part of breeding corns but the genetic part is still pretty confusing even though I'm working with some pretty simple stuff. Here's what I'll be working with: 1.1 snows, 1.1 amels, 1.1 butters. Will the snow x snow produce all snows? I'm looking to make some caramels. If I breed the 2 butters together will I get all butters or will I get butters, caramels, and amels. My male amel is 100% het caramel, would the outcome of breeding him to the f-butter acheive different results as opposed to a butter x butter breeding?

Which male should I use?

ButterXButter would yield 100% butter
butterX amel het caramel would yield 50% amel het caramel and 50% butter
SnowXSnow would yield 100% snow
snow and butter are very similar, technically speaking. They are both consisted of two recessive traits, one of which is Amelanism.
For Butters, the second trait is caramel, for snows, it's anery type A.
Try to think about it this way- each parent yields one of two genes for each trait(it's not a whole lot more complicated but if you would like to delve deeper, I suggest you take the time to read up some articles).
So if the father is an amel, it means he has two amel genes- and so, all of his offspring will get an amel gene as well.
Now if the mother is het for amel, only one of the trait related genes is the amel ones, so only 50% of her offspring would get it.

I would look for some websites about heterozygous genes. I will spare you my attempted explanation of how it works, but basically all the morphs of corns are colored differently because they have 2 recessive genes instead of 1 recessive and 1 normal gene.
You have to realize every snake has a PAIR of genes. One comes from the mother, one from the father. If either ONE of these genes is normal, the snake will look normal. The ONLY way a snake can show up as an, amel for example, is by having both those genes be amel.
That being said if you breed 2 amels, you'll get amels. This is because both your parent snakes are amel, so you KNOW they both have a pair of the recessive trait. Its impossible for your babies to be normal.
Now I'm no expert so my advice would be to take a look at some genetics websites. if you search google for corn snake genetics you'll get some really good links. Hope this helps!

So you would have to apply the example I gave to you for each of the morphs you're crossing. so the 100% amel het caramel X 100% amel het caramel would go down like this.
You know it's going to be amel something, since they're coming from 2 full amel's. the caramels will break down as 25% normal (still amel), 50% amel het caramel, and then 25% amel caramels. Does that make sense?
since both parents are 100% amel, everything will be amel something. Either amel caramel, amel het caramel, or just amel. But your caramel genes are going to get split up. some babies will get no caramel, half will be het caramel but they won't look caramel, and the rest will be your goal, amel caramel.

Thanks! It all makes perfect sense. I kinda figured it would turn out similar to that. I just thought I might get a caramel and didn't realize I would have some regular amels. Now I know! Thanks so much! So I'm guessing that a amel het caramel X caramel het amel is probally a lot harder to figure out?

I really really wish I could but my computer is down right now. I'm surfing on my blackberry and can't figure out how to download most stuff or even post my pics. Do they have an online genetics wizard. I've been to one called advanced genetics wizard (I think) but I can't get it to work right.

The most important thing is that with the material you have (snows, amels, butters) you're not able to get caramel in the first generation unless you breed your butter female to someone else's caramel male. Then you'd get all caramels het. amel OR 50% caramels het. amel and 50% butters if the male carries amel trait.
As all your snakes (snows, amels, butters) are homozygous to amelanistic, you're not able to get any "non-amelanistic" morphs if you breed them with eachother. No matter what two of these you'll mix together all babies get amelanistic gene from both dad and mom, so they'll be amelanistic + possible other traits they'll get from both parents.
amel: 2 amelanistic genes
snow: 2 amelanistic genes + 2 anerythristic A genes
butter: 2 amelanistic genes + 2 caramel genes

yep, looks right. Except in "25% normal het butter caramel"...you just have to say "25% normal het butter" because butter implies that there is amel and caramel.
