A 'het albino' will look like a normal colored black and brown ball python. It only has 1 copy of the albino gene.
The snake needs to have 2 copies of the albino gene for it to visually BE an actual albino, the yellow and white snake;and yes. using an actual albino in breeding will give you better odds than using a het.
