this may seem silly but what about the super spider? It doesn't exist? Just 100% of the clutch comes out spider and prob with woobles.
There are reports of possible homozygous spiders and pinstripes out there, and they consistently throw clutches of 100% morphs and no normals. They don't look any different from the single gene copy animals (hence them being called dominant).
Of course, i can't substantiate this because i don't remember exactly where i found it.
I dont believe that spider to spider breeding cause more wobbles either. Low wobble spiders can produce high wobble spiders and vise versa.
