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.
