in regards to viability. out of split over albino, most spawns were fertile, some only partial and a few with no viable eggs.
the biggest problem here is tadpoles developing (splits were similar but nothing at all compared to the extent the albinos get) scoliosis (bent backs etc). of all albino tadpoles produced less than 3% have made it to the frog stage looking normal. i do have one male that looks to be the full quid, once a bit bigger will spawn back to original albinos. will also spawn over split and see what that produces, may get some females? Also have access to a young female frog that appears to be of another line, was wild caught and is not so vibrant yellow.
so call it simple genetics or what ever anyone wants, but they are proving to be a challenge here. it will no doubt take some time to produce any number of quality frogs but not all is lost it is just going to take time.
