Well if she produced an Albino in the clutch you would be able to change her from a 50%(possible) het to a 100% het.
you could get
Albinos, Hets or normals if she is in fact a het. If she isn't a het then you would get hets and normals (hence 50% het)
The whole %het doesnt mean its a het per say. 50% or 66% het are the chances of said animal being an actual het. 100% het means it is a het, anything else is just a possible, a gamble.
