In the case of recessive traits, the animal has to have two alleles of the albino gene to be an albino. This means that they would have to have an albino gene from the father and one from the mother.
If you breed an albino to a normal, all the hatchlings will appear normal. They would all be HET for albino.

Here is a great site that has some info: http://www.ballpython.ca/genetics_101.html
