I don't think it's co-dominant or recessive to be honest. Just to be on the safe side, I wouldn't breed that gecko, though.
We had two show up with six toes on either the hind legs or all four...that was in late 2006 and I've never seen it again. I kinda freaked out at first because I've heard people say it is genetic in other reptiles, but the same adults are still together and I've never seen another one like those two.
