Crossbred is the same than hybrid? In this case I don't think so. It's the pure species, just one of the very common mutations that in captivity are more frequent to see than the wild form.
@Kakapo "crossbreed" doesn't have any proper meaning. It can mean a true hybrid (i.e. between two species) or it can mean between two varieties of domestics (e.g. if a bulldog and a dalmation produce puppies together then those puppies can be termed crossbreeds).
