Just to add to Joe Morlan's answer to Michael Conner:

That's right, of course. But suppose in some population albinism had a
selective advantage, or at least wasn't disadvantageous. Then the
population would probably accumulate some albinos and that would be a new
morph. There's no particular genetic difference, just a question of
whether or not selection allows a form to remain in the population.
