I have looked, but haven't found much information about what is exactly going on. The statements all say that EB to EB pairings result in normal looking babies. The next parts are a little more confusing. They say either that you can pair an EB with a "het" or you have to breed two "hets". I added the quotes because they obviously aren't true hets in the simple recessive sense of the term, but most people would recognize it as a descriptive term, if not totally accurate. Thanks for the publicity.
