Snow: Amelanism + Anerythristic, right?

That's what the FAQ says. So doesn't that mean, if you cross an amel with an anery you get a snow?


'cause. I downloaded the corn snake morph predicter program (on several comps :p ) and it tells me that if I were to cross an amel with an anery, I would get "100%, het for snow" meaning all normals, het for snow. I really don't understand that. :-/ I thought since amel = no black, and anery = no red, amel + anery = no black or red; just whites, yellows, etc. Why does the program say they will all be normals?



Just to check myself then, if it is right and all my... whaddya call a baby snake? Hatchlings! If all my hatchlings are normal het for amel, then if I bred that back to the anery.... I still wouldn't get a snow? According to the program I wouldn't. I would have to breed two hatchlings (once they were adults, obviously) to get a snow?


I'm really confused. :-/



Also, I know it's hard to tell the diff. between type A and B anery and it's mostly just the yellowness, right? Well my male I just got has a thin stripe of yellow from the chin to only a few inches down his neck. He's somewhere over a year old, and all the rest of his body is just gray (actually dark dark brown) and lighter grays. Would you guess type A or B?


Thanks for helping my pitiful self! (-:
 
Because they will be all normals. The two morphs are independant of each other, breed an anery to an amel would be like breeding an anery to a normal and an amel to a normal; in order to express the trait the babies must be passed two of the same genes from each parent. Snow corns are babies that are passed both amel and anery genes from both of the parents (in your example only one parent passed amel and the other parent passed anery).

So all the babies are normal, but all carry the gene for amel and anery. When you breed two of those together the snakes that are given both an amel and anery gene from both of the parents will be snows. I'm sure someone can explain it a little less confusing then me.
 
Anerythrism and Amelanism are both homozygous recessive genes, meaning that in order for each of those traits to be expressed there must be two copies of the gene.

Let's call amelanism "a" and anerythrism "b". So an amelanistic cornsnake would be "aa". A normal het for amel would be "Aa". An anerythristic cornsnake would be "bb", and a normal het for anery would be "Bb".

A snow cornsnake, on the other hand, would be "aabb", since you'd need two copies of each gene for that trait to express itself.

If you were to breed an amel "aa" to an anery "bb", you would get "ab", or reworded "AaBb", which would be a normal het for anery and amel, or snow. Breeding those babies to each other would result in anerys, amels, normals, and snows.

Just remember that for most cornsnake genes, you need two gene copies for the trait to express itself. Each parent can only give ONE copy of that gene, so the other parent must also carry that gene in homozygous (two) or heterozygous (one) form.
 
:dance: I get it now. (-: Thanks. I made myself an Excel sheet with all the genes and stuff on it, so that plus the explanations make sense now.



I believe my amel is het for something, I just don't remember what. And I have no idea on the anery's genetics. Just out of curiousity, are they more likely to be het for something in particular just because that'd be a more common breeding? Like, is it more likely my amel will be het for anery, or... I don't know what else? I know there's no real way to tell w/o breeding though. (-:
 
Most corns out there are het amel----and a very good portion are het anery as well. I'd say the percentages are higher that any given anery is het amel, and that any given amel is het anery.

So there's no way of knowing until you breed them, but there's a good chance that your anery is het amel, and your amel is het anery.
