Hello!
Either you have not registered on this site yet, or you are registered but have not logged in. In either case, you will not be able to use the full functionality of this site until you have registered, and then logged in after your registration has been approved.
Registration is FREE, so please register so you can participate instead of remaining a lurker....
Please note that the information requested during registration will be used to determine your legitimacy as a participant of this site. As such, any information you provide that is determined to be false, inaccurate, misleading, or highly suspicious will result in your registration being rejected. This is designed to try to discourage as much as possible those spammers and scammers that tend to plague sites of this nature, to the detriment of all the legitimate members trying to enjoy the features this site provides for them.
Of particular importance is the REQUIREMENT that you provide your REAL full name upon registering. Sorry, but this is not like other sites where anonymity is more the rule.
Also your TRUE location is important. If the location you enter in your profile field does not match the location of your registration IP address, then your registration will be rejected. As such, I strongly urge registrants to avoid using a VPN service to register, as they are often used by spammers and scammers, and as such will be blocked when discovered when auditing new registrations.
Sorry about all these hoops to jump through, but I am quite serious about blocking spammers and scammers at the gate on this site and am doing the very best that I can to that effect. Trust me, I would rather be doing more interesting things with my time, and wouldn't be making this effort if I didn't think it was worthwhile.

Homo x Homo (recessive) = what?
What would the poss. offspring be? Would they have to all be homo? or would there be hets also?
I have bred codom x codom and had normal offspring in the litter.

When breeding two homozygous animals to each other you should get all homozygous offspring. If both parents are also Het for another recessive trait, then you should produce some of those as well.
Example: Albino Leopard Gecko X Albino Leopard Gecko =
100% Albino Leopard Gecko Offspring
Albino Het Blizzard Leopard Gecko X Albino Het Blizzard Leopard Gecko =
25% Albino Leopard Gecko Offspring
50% Albino Het Blizzard Leopard Gecko Offspring
25% Albino Blizzard Offspring (expresses both recessive traits at the same time)
I hope this helps!

Can some of the animals be normal looking? This is why I ask.

07 MALE ANERY #1 THAT IS JUST AWSOME
--------------------------------------------------------------------------------
This guy was produced by me. Mom is an anery and dad is an anery. I bred his mom to two different males. The litter was half anerys and half double het snows. His mom bred to an albino male also. I can ship him overnight to your door. He is very healthy and just an overall very nice snake. I would prefer a Postal money order if possible. I might consider a payment plan if it was absolutly necessary.
MALE ANERY----$175.00 PLUS SHIPPING

The key to the problem here is that the female was bred to two males. The normal-looking babies were sired by the amelanistic (AKA albino) male. They could not have been sired by the anerythristic male. The anerythristic babies could have been sired by either male. If they were sired by the amelanistic male, he is heterozygous anerythristic.
Hope that helps a bit.

I actually think this is a possible scenario if the female was indeed bred to two different males. I have heard of such things happening with ball pythons.

In this case, IMHO, you can not list the babies as DH with accuracy. There is no guarantee due to the multi partner thing. Although the Anery's in the litter are obviously Aneries, and the normals are obviously normals, I don't think you can guarantee who gets what genes. You can only theorize that the Normals will have an Anery and an Amel gene.
Most likely like Paul stated, the normals are Het for albino, and the Anery's are just Anery's. I just don't picture any DH's coming from a pairing, or trio like that.

Well, mom is an anerythristic, so all the normal babies are het anery, no question. As you stated the normals would have to be het albino, so by default they are double hets.

I am not sure what is "absolute" when dealing with recessives, but I bred
2 f1 salmon boas together and got 20% normal looking boas (10salmon/3normal). Is it possible that the only father of the litter is the anery? I just do not know for certain

I'm sorta referring to how can you guarantee it? And if you can't they shouldn't be listed as DH.
I could be off, but it just seems in my mind, like you can only guarantee them as Het Anery due to mom.
Casey, you got normals in your Salmon litter, because both parents have a normal Gene to pass on. Salmon are literally Het for normal, unless they are Homozygous (Supers).

Ahh. Gotcha.
So an aneryxanery would have to produce all aneries because they do not have the normal gene?
