Bold Stripe geckos show a clear stripe of yellow that runs down the center of their back framed by solid lines of dark pigment. The sides of the leopard gecko’s body and tail usually exhibit additional black spotting. The stripe may extend from the base of the head along the body to the base of the tail. The black lines bordering the stripe vary in width and can either be broken or solid lines. There are still doubts about the genetics of this morph. It is not clear if it is an incomplete recessive gene or an incomplete dominant gene. This gene can be crossed into many other morphs to create great combinations of morphs.
