For any fellow science nerds, there’s a preprint of a potential new paper you can read about the iridophoromas associated with the Lemon Frost morph in leopard geckos (and leos as a genetic research model in general)! Looks like they worked with Steve Sykes, one of the first to originally work with Lemon Frosts. Gourmet Rodent hatched the first LF in 2012/13, and Steve Sykes (famed leo breeder, ‘Geckos Etc.’) got his pair at auction in 2015, the first Gourmet Rodent released. At present, Geckos Etc. does not appear to be selling Lemon Frosts.
I’m only partway through the paper, but before you click the link: this is not a publication from a peer-reviewed academic journal, it’s a preprint, a full research paper that has yet to be accepted for publication as of the date it was shared.
Edit: iridophoromas are tumors that form from iridophores, pigment cells that reflect light.
