Thanks for answering my question. I was just asking because that was an example from from a site that is a goto site for many newbies in the hobby and if I bought those you wouldn't know anything about them and there are many online listed the same way. Most things on that site are precise but if I bought those I would be asking the same questions. Oh and a cross of lines doesn't even say what lines, morphs, locales
I think real answer is people do it, just because people do something you shouldn't and it is frowned upon in the hobby. If you want to breed them pay $10 more and know for sure what you are buying. If you breed them anyway don't try and guess what they are it is to late. Just say they are Leucamalas because obviously they are that.
