So I'm flipping through WOB genetic wizard and I'm pairing up my highway (gravel yellow belly) to an enchi gravel to try and get some enchi highways. Thing is, I can also pair it to an enchi yellow belly and get enchi highways. How does that work? Gravel and yellow belly aren't the same gene are they? I'm kind of confused. Link in case you're curious.
