How do I know which is het. for what?

I've got 10 hatchlings - 3 anery het. amel & 7 normals het. for snow or amel.

But how will I know which normal is het. for snow .... and who's het. for amel ?

Offsprings are predicted to be...


50% het for snow
25% Anerythristic het for amel
25% het for amel

Does somebody have a clue ?
 
Perhaps another calculator will give you an indication, whether you are able to know it or not ;-)

Parents where Amel het. Anery x Normal het. Anery - right?
So, the optical result in your clutch should be:
3/4 Normal het.Amelanistic 66% poss.het. Anerythristic
1/4 Anerythristic het.Amelanistic

That means, take 3 animals out of the normals and you got 2 of them het. Anery and one not - but you cannot say which of these is het and which not. Thats why I used the 66% poss.het. XY notation.

Hope I could help you...
 
Hi Karolina. If I've understood your question, you want to know how to tell which of the Normal hatchlings are het for Snow and which are the hets for Amel? I'm afraid there's no way of telling by sight. The only way to "prove" a Corn's het is to wait until it's an adult and breed it with another Corn known to be carrying the suspected het.

Menhir's right - without that proof by breeding, you can only quote that a hatchling is "a possible het" and the likelihood of that het expressed as a percentage. You can confidently quote that all of your Normals are het for Amel, as Snow is an expression of both Amel and Anery. The het for Anery is only the 66% chance that Menhir's pointed out.

I'm in exactly the same situation, with 19 hatchlings from Amel het Anery x Normal het Anery parents (15 Normals, 4 Anerys). What I plan to do is label the Normal hatchlings as "NORMAL HET AMEL (AMEL HET ANERY x NORMAL HET ANERY)" and not mention the possible Anery het at all. If the buyer is experienced and looking for a breeding animal, then they'll work it out from the parents and decide whether to take the chance if they're looking for an Anery het. If the buyer is just looking for a pet, then a possible het won't matter to them.

One thing I want to add. The phrase "het for snow" is herper slang for "heterozygous for amelanistic and heterozygous for anerythristic". And the phrase "amelanistic, het for snow" is herper slang for "amelanistic and heterozygous for anerythristic". As one parent was albino and heterozygous anerythristic and the other parent was heterozygous anerythristic, ALL of your babies MUST be heterozygous amelanistic. Some are also heterozygous anerythristic, but the only way to find out is to do a breeding test when the babies mature.
 
Hi - I have a question on a similar vein.

Is there any way to find out if a snake is het for anything ie is there a test that can be done?

I have two corns one Amel and one Normal. The store that I bought them from could give me no other information.

Yep. But not the kind of test that your thinking of. As Kel said earlier, the only way to tell if your snakes are het for something is to breed it to animals that are homozygous for that trait you want to test.

But even then you could be extremely unlucky in the outcome and still not prove anything. For example, lets's say, theoretically, that your normal is het amel, but you just don't know it. You mate the normal with your amel and get all normal babies. You think that your normal can't be het amel because you didn't get any amels, but you would be wrong. Instead what happened is Lady Luck wasn't on your side and the amels just didn't show up, even though they had a 50% chance to.
 
Thank you for your help. Does it get any easier?

The way my luck is going at the moment I could breed an amel with a ghost and come up with this

I don't know if it gets easier. It can get harder. :D

If I mate an amelanistic to a possible heterozygous amelanistic and do not get any amelanistic babies in the first clutch (7 babies or more), then I figure the possible heterozygous amelanistic failed the test and is normal rather than heterozygous amelanistic. With 7 babies, the odds that I'm wrong are less than one percent. Good luck.
