Russo line het vs. Fire

Can anyone explain any visual differences between hets for blue eyed leucistic and black eyed leucistic hets. And would you produce a version of leucistic if you bred the two together. Also is it possible to have a snake that is high yellow just because of standard variations in normal. Thank you guys for your time your wonderful.

croft,
yes it is possible to have a high yellow normal. and there are differences between het blue and black eyed lucy. the het blues are mojave, lesser, butter, and russo line het blue. the black eyed hets are fire, and if you consider the ivory a low grade leucistic than the yellow belly would be het. the only compatable lines are mojave and lesser, if you breed russo line het blue to fire you'd get a cross. im sure some lines havent yet been crossed to see if they are compatable, i dont think the butter mojave has been done yet? in my opinion the super lesser makes the best blue eyed lucy. most of the others have yellow lines and grayish heads.
