My het hypo female also sheds patterend but her and her het father are both a couple shades brighter than normal as were right around half of the 50% chance het clutch I picked her out of. When I got her father about 10 years ago it was right after I first heard of some het hypos shedding clear so when I picked him up I asked the breeder who was specializing in the hypo gene if he had hets that shed clear. It just happened to be cleaning day and he want through his racks and found several clear sheds from het hypos. So I don't know how common it is but some het hypos are close enough to they hypo end of the scale to shed clear.
