The Ultramel is a recessive morph and is a single mutation from a WC founder. It is not a combo or anything like that. The original WC (VPI's) burgundy albino has made some F1 hets but no F2 Burgundy Albinos have been produced as of yet. In time I bet the Crider, Ultramel, and Burgundy albino will prove to be the same morph but from seperate WC founder lines. I love this morph and cannot wait to see what the future holds.
