What Hypo looks like

Dominant; reduces melanin producing lighter tones (lavender on black, pink on red)

Reduces melanin and dark pigmentation, producing lighter base coloration. Dominant over melanin. Multiple forms exist, all dominant. Hypo acts as an epistatic modifier over Black Base, Red Base, and Yellow Base. Creates Lavender (H+B), Pink (H+r), and Cream/C2 (H+y) combo morphs.

How to identify it: Hypo animals are noticeably lighter in base coloration. Multiple Hypo forms range from subtle to extreme lightening.

How Hypo is inherited

Hypo follows a incomplete dominant inheritance pattern, carried on the Hypo allele (locus H).

Combo morphs with Hypo

  • Lavender

    Epistatic color transformation: Hypo reduces melanin on Black Base, shifting black to pastel purple/lavender/blue tones.

  • Pink

    Epistatic color transformation: Hypo reduces melanin on Red Base, shifting red to neon pink or cotton candy pink.

  • Blonde

    Light yellow with yellow dorsals. NOT phantom - achieved through citrus (yellow base) with hypo.

  • Bubblegum Pink

    Hypo + Tangerine + White Pattern creating pink/bubblegum pattern coloration.

  • C2

    Cream-on-Cream (C squared) - unicolored animals that are all white. Usually a yellow base animal with high amount of hypo causing the yellow base to fade to white. Little to no dark coloration, reduced pigment under tail base and kneecaps.

  • Creamsicle

    Yellow Base + Hypo creating cream/orange coloration. Optionally enhanced with Tangerine and/or Red Base.

  • Silver / Grey Phantom

    Phantom melanin blending combined with Hypo lightening creates silver/grey coloration.
