Reference images of the Axanthic morph. Axanthic is a single recessive trait that removes all yellow pigment (but not red), often resulting in colors ranging from crisp grey and white to a washed-out brown color. An easy way to distinguish a low expression axanthic from a normal is to look at their bellies, which will be checkered with white specks instead of yellow or orange.

Reference images of the Toffee Belly morph. Toffee Belly (also called Toffee, for short) is a single recessive trait that removes some dark pigment (but not all). They are named after the toffee color their belly scales display. Their body scales range from light to dark browns, and soft or deep orange colors. Their tongues are a brown color, similar to their belly.

Reference images of the Evans/Dutch Hypo morph. Hypo is a single recessive trait that removes some dark pigment (but not all). Their bellies are often a golden/dark brown with softer brownish yellow checkers. Their eyes are a deep golden brown and their tongues are a reddish brown color. Their body scales range from light to dark browns, often with a nice orange or golden undertone.

Evans Hypo and Dutch Hypo (often just referred to as Hypo) are both the same genetic mutation/morph. One line originated in Europe, the Dutch Hypo, and the other line originated in the United States, the Evans Hypo. It has been proved that both are the same morph, so Dutch/Evans will often be used interchangeably and/or be referring to which line it originated from.
