Yes, I took WingedWolfPsion to mean homozygous spider or homozygous pinstripe, not the spider and pinstripe combo, but I see how it could be taken that way.

The latest info tends to eliminate pinstripe and spotnose as lethal but it should probably be considered a possibility for any new mutation until proven otherwise. Hard to say for sure on the spider and woma. Maybe the homozygous spiders never hatch or perhaps could never even get shelled/laid (not sure enough of the reproductive cycle to know if that is possible) and maybe one will yet be produced and proven out at long last. There have been a few rumors of hope for pearls but I haven't heard of any for sure adults.
