Only "hidden gene" lesser I know of are the platinums, or platty daddys, and those aren't called lessers. The whole point of the word "lesser" in lesser platinum is that it is missing the hidden gene that makes it a platinum.
If you cross a platinum with a normal, you get 50% lessers, and 50% hidden gene carriers. You can't have both in the same animal without it being a platinum. At least this is how I understood it.
