Nope because the odds are per egg, not per clutch. So it doesnt matter if you pair a spider, pastel and a pin to a female. No matter the male, each egg would have 50% chance of being a morph or 50% chance of being a normal.
The only way you could increase your chance of normals is if you were pairing a female with a super male and a single gene male because the super would give all morphs and the single gene would only have a 50% chance of producing a morph.
Oh oops, that's what I was thinking of. I knew it was chance per egg, not per clutch.
