Genes
| letter | gene | full name | traits |
|---|---|---|---|
| E | MC1R | melanocortin 1 receptor | eumelanin (requires signal molecule from agouti or defb) vs. pheomelanin ee produces a non-functioning MC1R |
| K | defb103 | defensin beta 103 (= CBD103 beta-defensin 103) | dominant black has a glycine deletion KB makes a signal that binds tightly to MC1R, preventing agouti expression |
| B | TyRP1 | tyrosinase related protein 1 | black (B_) vs brown (bb) |
| A | ASIP | Agouti Signaling Protein | ASIP promotes pheomelanin (aa: no signal, A_ signal with varying on-off patterns) |
