Motley Corn Snakes
Motley turns a corn snake's saddles into rounded shapes along the back, thins the side pattern to dots or a line and leaves the belly plain white. It shares a gene with Stripe, so a snake with one copy of each still looks motley and the stripe stays hidden.
About the Motley gene
The Motley gene affects the pattern. It makes the corn snake's back saddles rounded, removes most of the side pattern, and removes the belly checkers. The colour comes from other genes the snake carries. Since it changes the shape and not the colour, it sits under combinations like Caramel Motley and Snow Motley.
Appearance
Because the dorsal saddles of a Motley stretch until they touch, the back can look like a row of small circles or a ladder of rectangular or elliptical marks. These marks join most strongly at the front of the body, while the circles usually break into small blotches by the tail. The lack of borders on the saddles creates a clean look and usually leaves just two colours, like tan and brown or dark orange and red. Some animals look slightly hypo. The side pattern shrinks to a row of dots, a dashed line or a thin line. The head keeps the normal corn snake pattern, which includes a V behind the eyes and a band across the nose.
The most reliable cue is the belly. It is plain white without checkers, although colour often bleeds in from the tail end and a few scales can have small black freckles. A couple of stray checkers turn up very rarely. Whatever the colour genes make it, the body colour runs from brown through orange to red.
The pattern varies enough that several versions have names. Banded has saddles that run down the sides, Q-tip has some circles joined by a stripe, and Hurricane has dark rings around the circles. A Pinstripe Motley swaps the circles for a thin stripe of the ground colour along the back, either whole or breaking up along the body. It is still Motley: it has no connection to the Stripe gene and says nothing about whether the snake is het stripe.
Genetics
Because Motley is recessive, animals that are Het Motley, 50% Het Motley, 66% Het Motley or Pos Het Motley look like normal corn snakes. Motley and Stripe share a locus and make up the Motley complex. Motley is dominant over Stripe. A snake with one copy of each gene looks motley, but the stripe is not seen until it is revealed by test breeding. Such an animal is sold as stripe/motley or motley/stripe. A 2025 University of Geneva study in Genome Biology placed both alleles in the CLCN2 gene: Motley sharply reduces its expression, and Stripe is a retrotransposon inserted into it. Dr. Bernard Bechtel first produced Motley in the 1980s. Named combos are Lavender Motley, Snow Motley and Caramel Motley (also sold as Caramot).
