Thanks for the input. actually,"it" may indeed be "unique" for the simple fact that it doesn't seem to have a clear parallel in any other species that we commonly draw comparative conclusions from,whereas,"amelanism"(T neg.)for example,has a "universal" characteristic that can be seen in many other species."true hypomelanism" though somewhat variable,can also have the same universiality....comparatively speaking,a true"hypo" boa "should" look much more like the expression we see in some sub-adult/adult examples of tyrosinase positive "albinos",and,be recessive in its transmissive behavior...I would certainly agree that what we all currently accept as "hypo" in B.c.ssp. does result in a reduction of melanin,however,I've always felt that there is room,(at least in my mind )for the discovery,and,subsequent isolation of a recessive form of traditional "hypomelanism" that more closely mirrors what has been found in other species of animals.*(?)*
