The pinstripe mutation is a dominant trait, proven so in 2001 by Brian Barczyk of BHB Enterprises. The pinstripe gene does a similar thing to the pattern that the spider gene does: greatly expanding the tan/gold saddles of the animal, resulting in thin black lines throughout the animal; however, the pinstripe does not have the varying white along the sides from the belly up, but rather only white highlights along the black "pinstripes." Pinstripes' eyes are not green like the spider; in fact, most pinstripes have normal-looking, dark eyes, where the vertical pupil is not easily distinguishable.
We have a male pinstripe 100% het hypo in our collection. We most certainly plan to produce some pinstripe hypos in the future, and we are currently considering a project with our neighbor Quiet Tempest Reptiles about doing a jigsaw (pinstripe mojave) project. Still not yet sure what other project(s) we might work our pinstripe into, but you can be sure we'll think of something!
