For anyone staring at this too long:
| Phenotype | Genotype(s) | N | Allele Note |
|---|---|---|---|
| Green | bb only |
4 | b is recessive, needs two |
| Blue | Bb or BB |
12 | B is dominant, needs just one |
| Mike | aa only |
4 | a is recessive, needs two |
| Sully | Aa or AA |
12 | A is dominant, needs just one |
So Blue and Sully win out in most scenarios by default
