a)Many of the white shells sold as "albino" specimens, probably are
not: it is not possible to tell the difference between a totally white
color morph (common enough in some species!) and a true albino, just
by looking at the shell: Albinos lack the ability to form pigments -
so the animal would also be pigmentless (with red eyes, i wonder?).
So, without seeing  the animal, one cannot really say for certain
whether a white specimen actually came from an albino snail!!
b)I will re-iterate the question of Mr. Barclay - are some families
more or less likely to produce albinos?? If not, are there some
families (or species) more or less likely to produce ADULT albino
specimens (ie, are albino specimens less viable in some families or
species, than in others?)
Cheers,
Ross.
