In order for simple recessives to show themselves (homozygous) BOTH sides of the allele must have the desired gene. If not you will get the wild type expression of the particular animal. For example:
Breed albino to a genetic stripe. Both animals give off nothing but homozygous genes, but they won't line up on a single allele together. Therefore you hatch all normal looking offspring but they all WILL carry both genes hidden by the normal colors.
By using the the theory you describe, when breeding an albino x genetic stripe the ENTIRE clutch would be albino genetic stripes. And we all know it is not that easy to produce a double homozygous animal.
If you expand your square to how Mr. Benfer described it should help figure out why normals will appear in your clutch.
