Gravel is co-dominant: one copy produces a visual Gravel, and two copies produce the Highway. Breeding a Gravel to a normal gives about 50% Gravel babies.

Gravel is allelic with Asphalt, Specter, Yellow Belly: they sit at the same spot on the chromosome, so an animal can carry at most two of them, and pairing them produces combination morphs.
