What causes the difference among the albinos where some are extremely white with bright, defined yellows, and some are white with almost watered down, blended in yellows...
I love the lighter yellow shades, but I don't know what the different terms are or what is considered more desirable/popular/rare
High contrast albinos are usually more sought after than washed out specimens..The difference is in selective breeding efforts.
..,and that "snow" is actually the combination of two genes;albino AND axanthic (which reduces yellow).
