Hypomelanistic or Hypo refers to leopard geckos which exhibit reduced melanin or black coloring. 
No history yet.
To be considered a Hypo rather than a High Yellow, a leopard gecko must have ten or fewer spots on its body (excluding the head and tail). If the gecko is all yellow with no black body spotting, it would be considered a Super Hypo.
