I think so, but am not positive. The irony (hypocrisy) is that AZA zoos all have albino or leucistic reptiles and seem to have no problem with that, but if a zoo has a white tiger they are looked down upon.
The document on the white tiger/other color morphs ban also made mention of albino and leucistic animals in general. They take more issue with breeding than display. Do lots of zoos try to breed white alligators or something?
