So just an update and a bit of info that I missed until today. Worms 1 and 4, which I suspect are carrying the YB gene also exhibit a two toned eye. The other 3 are dark/black. Is this a marker? I don't know so any info would be appreciated. All taken in though I'm really happy with the clutch. Two ate day before yesterday and the odds gods were really in my favor with not a single gene among them.
