Request to add new gene - ChoCho Crested Gecko

Gene Request Form

Species: Crested Gecko C. Ciliatus
Name of Gene: ChoCho
First produced by whom: Sunju
Year First Produced: 2021
Genetics Type (Incdom/Codom/Recessive/Polygenic/etc): Recessive
In complex with other genes?: No
Other names/aliases for it?:
Description: This genetic alters the way red/tangerine is displayed on the animal. They hatch in a variety of tangerine/pink coloration on the cream parts of the animal, and the main base color is always a maroon red. As they age, they transition through many shades of pink/grey and darken with age.

Appearance; What it does/looks like?

  • Head: Dark Red head stamp, the red color is typically darkest on the head/neck region. Eyes are usually a lighter grey/blue color.
  • Body: Coloration is typically maroon at hatch, but gradually darkens with time. The lighter portions of the body that are typically cream, are covered with a tangerine layer of pigment.
  • Belly: Consistent with body color, often being the maroon color with a tangerine striping.
  • Tail: Variations of Pink/tangerine coloration coating the white portion of the tail that lead to a grey/darker tip.

Proven Lines: Sunju’s Main Line
Related Genes:

Proven: I have personally proved out 50% poss. hets, and have produced nothing but “normal” offspring by pairing our visual animal to unrelated animals. We have also produced these using Visual x 100% Hets, which yield expected results as well.
Unique: Why do you believe this is a new morph and not an existing one? The color pallet unlocked with this genetic is not something you will observe in any WT gecko, or any other common morph. There are “red” crested geckos, and there are ChoCho’s. Chocho has such a distinct appearance change right out of the egg. Reds often times hatch a brownish color and gain color with age, these do nearly the opposite. They hatch looking radioactive and darken with age.

Problems: Any problems? None to date to my knowledge.
History: The gene was developed by Sunju in South Korea. It first popped up out of a pair of tricolors back in 2020. After years of work and outcrossing, he proved the genetic out to be simple recessive, and in 2023 Ruby Reptiles became the first breeder to begin working with the morph here in the states.
Disagreement or Controversy: None

Attached are numerous hatch photos of Visual Chocho’s and Visual Lilly White Chocho’s side by side with their “normal” or Lilly White hatch mates. This shows clear evidence of this being a unique trait.
