A 66% het albino is a snake that has a 66% chance of being het for albino.
When you breed 2 het albino snakes together, the offspring would be
25% het albino,
50% het albino,
25% normal.
Since you cannot tell the hets and normals apart by just looking at them, all the normal snakes would have a 2/3 chance of actually being het, hence 66% hets.
50% hets are produced by breeding a het to a normal, where half the offspring would be normal, and half het, thus a 1/2 or 50% chance that a random offspring is het.
100% or just 'hets' are made when breeding an albino to a normal, or an albino to a het albino. In either case, all the normal-appearing offspring will be het.
PS - 'het' means heterozygous, since albino is a recessive gene, 2 copies of the gene are necessary for the snake to appear albino. A het animal only has one copy of the gene, so it appears normal, but is capable of producing albino offspring if bred to another snake carrying the albino gene.
