Regardless of the form,is not a trait that is expressed in "degrees"...In other words,when expressed in their homozygous state,which is the only condition in which they are visible,both tyrosinase negative & positive forms of amelanistics are quite obviously albinistic in appearence.(notable exceptions in boas,for example,often refered to as "paradox" are in fact examples of a defect within a defect,in which the biochemical process that would normally block,or,inhibit certain types of tyrosinase production,are,for reasons not fully understood,"incomplete",ie;"defective".) the animal in your post above,may come from a line that produces albinos,but,I see no evidence from the photo that is expressing any known form of amelanism.(sometimes T positive albinos are at first confused with hypomelanistic expression,(and,vice versa.)however,one quick examination of the eyes usually erases all doubt,T positives have ruby red pupils,sometimes the use of a small flashlight is neccessary to truely see this,with small colubrids.)
