True Ghost Pic Request

[MPenn]

confused on why this is a True Ghost?

Hypo/Ghost = Yes, Axanthic = Yes
Axanthic/Hypo (True Ghost) = ? just dont get it

Maybe a Hypo Lucy?

Because, in any other species, a ghost is a double homozygous hypo axanthic (or anery).
Example; a ghost corn is the expression of hypo and anery.
