i've seen u post these BP's a few times asking for morph ID or feedback. while i'm not familar w/ these morphs, these are my thoughts...
he looks like a visual Caramel Albino lol. doesn't look Lace Black Back at all to me. the colors are all caramel to me. what colors are his eyes? are u sure the YB father wasn't also het?
what does the belly look like on this one? i think it's just a beautiful, dark and super reduced Het Caramel Albino. can't be HRA either - their patterns are similar to Cinny. cannot be Lace Black back as it doesn't resemble it pattern wise and doesn't have the whites coming up from the belly.
both HRA and Lace Black Back being co-dom gene's, i think the parents would have resembled those morphs in some way. could u post the parents of the 1st one also? do they look like a standard YB and Normal?
