Just when i thought i knew genetics...

[Vicic17]

Hey guys.

I have been really studying the genetics in corn snakes, i am now able to tell what most morphs are, and what they can make if bred to certain other morphs, however, we recently picked up a nice 07 bright orange creamsicle, to pair with our 5 foot amel motley.

I don't know much about hybrid snakes, however i do know that creamsicles come from: Cornsnake (Elaphe gutatta) X Great Plains Ratsnake (Elaphe emoryi) + amelanistic

here is where i become confused...

will we just get normals and amels? or will there something else happening in here?

thanks..

Nick.

Pretty sure you would get amels assuming there are no similar hets.

I think you would get all creamsicle het motley or basically all amel het motley but they would all have a bit of Emoryi blood so I think that means that they should be labeled creamsicle. That's just my understanding & might not be right.

I think that would be a good plan.

All creamsicle het mot. Normals from the cross would be called rootbeers.

Ohhh okay, that clears up a lot, i knew it would be something similar to this, i just wasnt sure about the normals.. somoene also said something about okeetee's, which are also 'normals'

so Creamsicle Het Mot and Rootbeers is what i'd get? what other possibilities? or is that it. I am not sure if the Corncalc has hybrids on it :S:blowhead:

You would get all creamsicles het motley because both parents are homozygous amel.

Okay, that makes things a lot clearer, so if i held some back and grew them up and bred them together, i'd get??? amel mot? creamsicle mot? lol, man.. why did i have to get a hybrid snake, so much more confusing!

The names "Creamsicle" and "Rootbeer" are simply names for 1) amelanistic animals with a mix of corn and rat heritage and 2) normal animals with a mix of corn and rat heritage, respectively. Those are names that designate hybrid status. So, no matter what you breed down the line from this animal, you will have to use the hybrid common names to refer to them, not the cornsnake common names. That means if you breed the F1s together, you will get 1) some animals who are homozygous recessive for both amelanism and motley and 2) some animals who are homozygous recessive for amelanism and either heterozygous for the motley allele or homozygous normal at that locus. If they were pure corns, you would call group one amel motleys and group two amels, which denotes their phenotypes. But since they have ratsnake heritage, you would have to call them all creamsicles rather than just plain "amel," to denote their hybrid status.

Once you have the genetics down, you still have to know what all the common names refer to, and the latter is not particularly systematic.

It doesn't make things more confusing, you just have to call everything by the hybrid name.

First generation: all creamsicles het motley (genetically amel het motley)
Second generation: creamsicles possibly het motley and creamsicle motleys (again, genetically all amels)

From hybrid parents:
Amel = creamsicle
Normal = rootbeer

Edit: Looks like Stephanie beat me to it.
