Looking at your previous posts, it looks like you have a normal female and are looking to buy a 50% possible het albino. I assume that you are looking to produce albinos. If you are, and you can't buy a homozygous, I wouldn't purchase anything other than a 100% het.
Breed a 100% het to your normal female will produce all normal looking offspring, but they will be 50% possible het for albino. (half will carry the albino gene, the other half will not.) When the offspring are old enough to breed, mate the 100% het father to any female offspring. If the daughter is a true het, than you have a chance (25%) of producing a visible albino. If the daughter does not carry the albino gene, than your back to producing 50% possible hets. Basically its a crap shoot.
If you can buy a homo and breed it with your normal female, you will produce 100% hets. When old enough, mate any daughter(s) with the father and you have the best chance (50/50) of producing more albinos from any resulting clutch.
For additional info, I recommend going to NERD and reading the genetics info pages. These help me to understand what little I know. Hope it helps you.
