Genetics is about 100% and 50/50's.

Homozygous (Super) X Normal = 100% Heterozygous

Heterozygous X Normal = 50% Heterozygous 50% Normal

50% of the genetics come from mom, 50% from dad.

Spider (S) X Normal (N) = S, S, N, N

Pastel (P) X Normal (N) = P, P, N, N

Bumblebee (SP) X Normal (N) = to make it easier, start with one gene (S) which gives us S, S, N, N and then each of those has a 50/50 shot of also carrying the Pastel gene. SP, S, P, N.

Super Pastel (PP) X Normal = P, P, P, P 100% of offspring inherit the P.

So add a P to SP, S, P, N = SPP, SP, PP, P
