Fig. 1

Color pattern of wild-type, Motley, Stripe, and Motley/Stripe corn snakes. A The wild-type pattern consists of dorsal and lateral blotches and black and white ventral checkers. B Motley individuals present elongated dorsal blotches that tend to fuse, especially at the anterior part of the body, with highly reduced lateral blotches and white ventral scales. C In Stripe individuals, the dorsal and lateral blotches are replaced by four stripes and the ventral scales are also white. Both the motley (mm) and stripe (ms) alleles are fully recessive to the wild-type allele: mm/ + and ms/ + individuals exhibit a wild-type phenotype as in A. D The phenotype of most mm/ms animals is intermediate, combining fused blotches and stripes
