The original pair of sibling animals I purchased were produced by my friend Tim Frazier. Tim purchased a very high yellow male animal that, if anything, appeared hypo. Other than the fact it was stunning in appearance, he had no history on it at all. Tim put it with one of his adult females and that male died (froze to death after escaping from it's enclosure). Thankfully, the female had taken, and I obtained my pair from this breeding hoping the yellow trait would carry on as a recessive trait.
Tim no longer is involved with breeding and couldn't provide more information when I contacted him three years ago when I told him I'd produced a very unusual looking animal from his "hets". I'm very lucky and excited to continue working to prove out the genetics and feel great things lie ahead!
