Gah, how many times does this need to be addressed? ROFLMAO
"However, I've never viewed them as a "lucy". To me a pure white snake is a Lucy and nothing else. A dark grey head with a light grey body in my mind doesn't qualify as "lucistic". An interesting looking animal but Lucistic it is not........."
Piebald = Partial Lucy
Homozygous Mojave = Lucy
Ivory = Lucy
Lesser x Lesser = Lucy
Snow = Phenotypic Lucy
etc etc.
Doesn't matter "How white' or how purty you think the snake is. If its lacking patterning, and is predominantly white, then yes it IS a lucy. Good example is the Snowball (Albino Axanthic). Genotypically, this is not a single trait lucy, but it is indeed a phenotypic Lucy(well the cleaner ones that have almost no patterning showing through would be considered a phenotypic lucy).
Stop thinking "How clean is the white defines a lucy" and start thinking "Is there a pattern to this animal?" that's alot more helpful in definining this than how purty it is LOL.
