100% het means the seller/breeder of that animal is absolutely positive the animal carries the gene it is het for. This means one of it's parents is a visual of the morph. A visual pied bred to any other morph or a normal will not produce ANY visual pied babies. BUT all of it's offspring will be 100% het pied. They will all carry the pied gene.
When you breed a het animal to another het animal is when you get in to 66% and 50% hets and so forth. A 100% het albino bred to another 100% het albino is a good example. Statistically out of 4 babies you will get 1 visual albino, 1 non het completely normal baby and 2 het carrying babies. The problem is, you cannot visually tell the hets from the non het, so you call the babies who are not visual from that pairing 66% het. This means 2 of the 3 are het, but until they are bred to another albino animal, you can't say which ones are.
Same basic principal with 50% hets. If you bred a 100% het pied to a spider for example. You would statistically get 2 spider babies, one of which would be het pied, and 2 normal babies, one of which would be het pied. But again, since you cannot visually tell the hets from the non hets, you call those offspring 50% hets. You have a 50/50 shot at any one of them being het for pied.
Did that make any sense at all ?
