I was wondering if the allele for anery A is dominent over anery B or vise versa, main reason i am wondering is if i am too breed an anery A and Anery B both het for albiniswhat would i get?

Well... the problem with that question is while one gene may be dominant in one case, it may not be dominant in another...

For example:

Lavender + AneryA = Lavender (AneryA is masked)
Lavender + AneryA + Amel = Snow (Lavender is masked)

AneryA + AneryB = AneryB (AneryA is masked)
I don't recall offhand whether adding Amel to the list would yield snows or blizzards...

Finally, to answer your question...
(AneryA + het Amel) X (AneryB + het Amel) =

1/4 Normal + het AneryA + het AneryB
1/2 Normal + het AneryA + het AneryB + het Amel
1/4 Amel + het AneryA + het AneryB

Or in plain English, AneryA het Amel crossed with AneryB het Amel will yield roughly 3/4 of the clutch as normals het for AneryA, AneryB, and 66% possible het for Amel. The other roughly 1/4 of the clutch will be Amels het for AneryA and AneryB.

The reason you don't get any AneryA's or AneryB's in the F1 generation (the first generation), is because neither snake is het for the other type of Anery, and AneryA and AneryB are not codominant. Thus the wild-type gene trumps both, and neither is expressed in the resulting offspring.

I've heard that Caramel masks AneryA, but I haven't heard anything about Lavendar masking it too.

Have you done breedings to determine this or have you just heard this from some one else (perhaps Rich Z.)?

It's very interesting.

I would think that if Lavendar masks AneryA, then adding Amel would create an Opal not a Snow.

And how could you tell an AneryA from an AneryB once you mix them together? Are they really that different in color when they are born?

Just curious.

Yes, Amanda... my information comes from Rich Z.

He's bred Anery As (het lav obviously) and gotten lavenders, and bred snows het lavender and only ever gotten snows... According to him, the numbers are such that it would be extremely unlikely to be just the result of bad luck.

In theory, if lav always masked anery A, you'd get opals in that bunch... and if anery A always masked lavs, breeding two anery As should never yield lavs... yet they have.

What this means is that even if X masks Y normally, adding gene Z can have an entirely different effect. Makes things more interesting for us cornsnake breeders.

AneryA and AneryB look somewhat different as hatchlings... but, atleast to me, they look very different as adults. I'm sure there are some borderline specimins, but with a decent enough picture, I can usually distinguish between the two. Think of AneryB's as looking as if they were drawn and colored with a charcoal pencil...

The charcoal hatchlings I've seen are different enough from AneryA hatchlings that you should be able to pick /most/ of them out if you mixed young hatchlings together. Just look for the ones with the darker background and lighter saddles...

Thanks but i am not shure that the wild type would be expressed because it would not be present as anery is rescessive so it would be aa rather than Aa or AA.
Thanks and i know some basic genetics from my grade 11 bio course

You said you were planning on crossing an AneryA het Amel with an AneryB het Amel, yes?

That's, if Amel is 'a', AneryA is 'x', and AneryB is 'b' (and capital letters are wildtype)...

AneryA het amel: aAxxBB
AneryB het amel: aAXXbb

So aAxxBB X aAXXbb =

1/4 aaxXbB (1/4 amel dh aneryA, aneryB)
1/2 aAxXbB (1/2 normal th aneryA, amel, aneryB)
1/4 AAxXbB (1/4 normal dh aneryA, aneryB)

Thing is, anery A and B are totally seperate genes...they aren't compatible (like anery and amel aren't the same gene), so the offspring will be het for a & b, but not express either.

Would it help to keep them straight to call aneryA by the name anerythristic (symbol ax = anerythristic, Ax = wild type) and aneryB by the name charcoal (symbol ch = charcoal, Ch = wild type)?

Mating an anerythristic (ax//ax Ch//Ch) x charcoal (Ax//Ax ch//ch) produces wild type snakes that are heterozygous anerythristic, heterozygous charcoal (Ax//ax Ch//ch).

Anerythristic and charcoal are mimics, meaning they are independent mutants that produce similar phenotypes.
