Genetics Questions

turtlesstartedit Jun 28, 2008 01:26 PM

2 seperate questions actually:

1st, Is a sunglow amelanistic and hypomelanistic? If you bred it with a normal het for nothing (I know, extremely rare) would your offspring be normal het for amel and hypo? If you took those offspring and mated them to a hypo, would you get some hypos?

2nd, Is the stripe a all or nothing trait? For instance, if you mate a stripe to a normal het for nothing (I know, extremely rare) would you get normal het for stripe? Or would you get an intermediate form like motley or Aztec?

Thanks in advance for your help,

Zach

There were a few people that used hypo to try to enhance their sunglows but I would guess that the highest percentage of sunglows are simply selectively bred amels.
IF you happened to have a sunglow that was homo for (expressing) hypomelanism and amelanism and bred it to a normal you should/would get normals het amel het hypo...if the normal had no hidden hets.
now take these normals het amel het hypo and breed them to a hypo you should/would/could get normals het hypo possibly het amel and hypos possibly het amel.
Now this is all assuming there is hypo in the sunglow....and my guess would be...probably not.

If you bred a stripe to a normal you would/should get normals het stripe.
breed these normasl het stripe together and you have about a 1 in 4 (25%) chance of getting stripes.

Thanks, but some clarification please.

What is the corn snake equivalent of a hybino, specifically amel and hypo? Do you have any pics? I have not come across this combo, though it seems like it should exist.

Also, what about anery A and caramel (hyperaxanthic)? Seems like this should be like an anery A with lots of yellow, but perhaps the anery blocks the hyperaxanthic. Can't believe no one ever tried that combo...

Thanks again,

Zach

Amel masks hypo - the only way to know you have a corn that is homo for both is either breeding trials - or if you have an albino that was produced by pairing two hypo's.

At least with HypoA. I don't know about sunkissed and lava flavors of hypo.

With respect to caramel and anery, I believe anery masks caramel. I believe that combo has been tried.

I don't know if AneryB and Caramel have been tried, but I suspect AneryB would mask Caramel as well.

according to the 2008 cornsnake morph guide (by charles Prtizel)

"anery Caramel It appears that caramel is unable to exert its influence when anery is showing. That is, caramel is masked by anery.As a result, these individuals are expected to look like any other anery. "

As for the Charcoal AKA Anery B Caramel

"Charcoal Caramel is currently unknown"

But i, personally assume if Anery A has no influence with caramel, i would assume anery B has no influence. I'm sure there are some out there but there isn't a visible difference from any other anery A or B.

Just a note -

Normals het for nothing are not extremely rare. Most locality lines are het for nothing. IE - most Abbott Okeetee's are het for nothing.

Lee Abbott told me an e-mail the only morph he has seen pop out of his Okeetee line is Sunkissed, but my guess is the vast majority Abbott Okeetees do not carry that trait.

(the Amel Abbott's that you sometimes see advertised are actually an outcross, and involve non Okeetee locality mixed into Abbott line - personally I don't think they should be called Abbott because from my understanding, his line is Okeetee locality, and the name of his line should therefore indicate locality)

There also are from time to time oddball county locality animals sold by hobbyists who collected them and bred them (check the classifieds here), and they usually are "het for nothing" unless otherwise noted - but sometimes, they may carry an unknown trait, and that's fun to discover!

I'm guessing that most non locality normal corns probably are normal byproducts of morph breeding projects and quite likely het for something, but if you want "het for nothing" look for locality lines.

Some localities are very fascinating, and extremely unique in the trade - if you want something different that isn't a morph.

If I had the space, I'd buy a bunch of different locality animals that are F1 or F2 - just to have snakes as close to the wild phenotype of a known locality as possible. The natural variances can be very fascinating.
