If there were, they'd really only be coming from Don S and his friend who discovered this trait, not a no-name in KY. The pricing and the fact that he's apparently letting the very first snow tessera (which should be at least a year away from realization, if you were lucky with your hets) go for around $500 while normal tesseras still fly for upwards of $1000 at SMR makes me EXTREMELY cautious.Pricing was a concern for me as well, not to mention, some one correct me if I am wrong, but aren't Tessera's new enough that there should not be other color morphs yet?

Tessera is a pattern modifying gene which is not recessive to wild type. Preliminary results suggest it is probably dominant.
The advantage of dominant and codominant genes is that they can be propagated more quickly into visible morphs, and the difficulties in dealing with and testing out possible hets do not exist because heterozygotes express the mutant gene.
The mixing of this gene with others will be accelerated by the fact that a snake only nees to be heterozygous to express it. When crossing het parents, 3/4 of the offspring will be Tesseras instead of the usual 1/4 that occurs with recessive genes.
Tessera is never likely to be a major money-spinner, as it's so easy and quick to reproduce (as explained above). That might explain the price. You won't pay top dollar for a new morph, that will basically be everywhere by the time your animals get to breeding age.
I thought the big deal about Tesseras was they retained a black stripe unlike "normal stripes" that lost theres? Where is the Caramels black stripe?
