The lightness coming through in hets makes sence to me. A few folks had mentioned white or albino random scales on hets, I'd think that was also a good marker. Calicos seem to be hets that have the albino underneath showing through in an extreme form. If all the hets have this "albino underneath" that would explain why they have these random light or albino scales, the eyes and the light saddles.

As far as some of this fading as they mature that would makes sence too, look at some t albinos they are born very light and may or maynot gain pigment with age.

I think the random white or albino scales would be more of a developing with age rather than fading with age just because thats the way that seems to go, on hets I have observed.

I was thinking a het leucistic would have to be a light colored boa just because in every other type of het leucistic pythons and such the het form is light..

good stuff

Just my .02 cents..
