What is going on here: http://www.premierpet.com.au/ALR100_...P-ANGEL/pd.php

I use to breed a lot of kribensis and know that in Krib albino is not dominant or recessive, but is instead co-dominant. So AA individuals will be wild-type, aa will be full albino but Aa individuals are albino leaking some colour (usually yellow).

The information I have seen so far here indicates that albinism in angels is recessive... so.. is there more than one type of albinism in angels? Is there a co-dominant form as in Krib? If not, how does one explain the above albino redcaps?
