Yes, very interesting. 20+ years into this project about time we get to the bottom of if spider is co-dominant or dominant. Best of luck on another couple good clutches that should be enough to "prove" it one way or the other. I know TSK produced some spider X spider clutches a few years back but I think most (all?) of their holdback spiders to put this to the test where female and harder to eliminate or prove the girls. If he does hold up would be really nice to know if he actually came from a spider X spider clutch or not.
