Before my eggs hatch and the percentages tell me... Is their a way to visually distinguish between an adult light amber corn and an Ultra amber ? Any clear definitive trait or rule I will be able to spot ?

also any info or web-links on the Ultra gene and the spin off morphs available, and who has them would be appreciated. I want to work with some more types !

thanks,
Jeff Serrao

To answer your first question: no, not really. If you look at where your snake came from breeder-wise, you could have a good feel, but the homozygous ultra form is not easily distinguished from homozygous hypo A. The EASIEST way to tell whether a snake is carrying the ultra gene is to breed it to something amelanistic. If you get ultramels and amels, it's het ultra/het amel. If you get all ultramels, it's ultra.

Hypo A, Caramel (Amber) vs:

Ultra Amber (hypo A, ultra, amber) - unknown
Ultra Caramel (ultra, caramel) - unknown
Ultramel Caramel aka Golddust (ultra/amel, caramel) - look for hatchlings that look halfway between an amber and a butter... ruby eyes are a good 'tell'
Ultramel Amber (hypo A, ultra/amel, caramel) - Probably similar to Golddust, although nobody's definitively identified a Hypo Golddust as being such.

Existing known ultra/ultramel combo morphs are:
Golddust (ultramel caramel) -- Rich Z, Joe Pierce?, myself?
Golddust motley -- Rich Z, Joe Pierce, myself
Ultramel motley -- Rich Z, Joe Pierce, myself
Anery ultramel -- Don Soderberg
Lavender ultramel -- Stephen? (possibly)

Most of the existing morph combos out there are with the ultramel geno/phenotype, since it's codominant with amel and therefore easier to create mixed combos. I think there may be a few ultra-only combos along the caramel lines, but I couldn't tell you who might have those or be breeding those.

First off thank you very much for the thorough reply, very helpful !

They are from Mike Shriver and Mike Falcon here locally. I know they had the "Ultra" gene in their collections before it was really named or identified.

Know of any websites with any "ultra" info or pic's ?

thanks again,
Jeff

Yeah, but I'm not sure it'd get past the forum filters.

I don't get to spend a lot of time on the forums so I'm not sure what that means ?
