No, it isn't quite that easy. Pieds and Albinos are both Recessive genes..so check out this chart...hopefully it will help you

Also take a note on this concept...it's a bit confusing at first, but you'll get the hang of it:
when talking percentages, 100%, 66%, 50%, that simply means there is that CHANCE of them carrying the gene. So if you have a 50% het pied, that means there is a 50/50 chance that it IS HET pied...that also means there is a 50% chance that it IS NOT HET (it does not carry the gene to produce pieds)
As for your rack system, I have a Vision CB-70 rack and I am happy with it.
