UPDATE 2025 - NEW INFO COMING SOON
I believe we have an entirely new gene that looks like Snowflake (in much the same way a good Whitewall looks like a Lilly White) but it seems to work like an incomplete dominant gene with an incredible homozygous or super form.  The above gecko is not a Lilly, but a combination of Snowflake, Whiteout (Whitewall) and Extreme Harlequin.
