Although it may be a bit late, we are now sharing our conclusions based on various experimental results, observations of different specimens, and discussions with multiple breeders.

Sable can be considered a recently discovered morph. Sable originated from a specific gecko pair that became known in 2017. The gecko, well known as the origin of the Sable morph, is named Rialto. Sable originated in the United States at Gecko Haven in Gettysburg PA. One characteristic of the Sable morph that we can confidently state is its significant influence on the genes responsible for white coloration in geckos. While some Sable individuals tend to lose some of their white coloration as they age, it is clear that Sable enhances white pigmentation. Additionally, the Sable morph shows dramatic changes as it grows, which can often be seen in Lilly White, Cappuccino, or Tricolor. Its appearance changes significantly from the baby stage to its juvenile stage and then again as it reaches adulthood.

In particular, as they grow, Sable geckos show a strong influence on the white coloration of the crown, enhancing the white areas on the head. Additionally, the white markings on the dorsal area become more pronounced, with an increase in noticeable white patterns.

Due to its trait of enhancing white coloration, we have personally observed that when Sable is combined with high-quality tricolor drippy traits, it produces exceptionally beautiful geckos. Additionally, when Sable is combined with morphs that enhance white on the dorsal area, such as super stripe, it produces incredible results that are truly remarkable. When Sable is paired with Lily White, the white coloration becomes even more emphasized, and there’s a noticeable suppression of the characteristic fluorescent yellow of the Lily White morph. When they reach adulthood, their appearance can be quite similar to that of a Frapuccino morph. However, in terms of white coloration, it is distinctly more pronounced compared to the Frappuccino, showing a clearer, more intense white.

The Sable morph also has a superform, known as the Super Sable. This gecko gives off an almost alien-like appearance, similar to the Super Cappuccino. However, the key difference is that, unlike the Super Cappuccino, the Super Sable does not seem to cause any genetic issues.

Also, as juveniles, Sable geckos display the distinctive dotted line pattern on their tails. However, the unique pattern cannot be used as the sole criterion for determining Sable. The easiest way to identify a Sable when it's young is by its thick tail. In the case of first-generation Sables, you can observe a phenomenon where the tail is divided into three distinct segments. These days, with the Sable morph being combined with high-quality Tricolors and strong Pinta-type individuals, it has become a bit more challenging to differentiate them from the first-generation Sables. Additionally, there is a tendency for a distinct white crown to appear from a young age. In terms of color, a light purple hue is also visible.

As many people are aware, there seems to be a connection between the Sable and Cappuccino morphs. When Sable and Cappuccino morphs are bred together, a very unique-looking gecko called "Luwak" is born.

I’ve heard from some people that Luwak, due to the influence of the Cappuccino morph, may have issues with small nostrils a bit. The specimen we imported from Korea to the U.S. also showed this small nostril issue a bit as well. However, it wasn’t as severe as in the Super Cappuccino, where the nostrils are almost invisible.

Now, people are testing the combination of the recessive gene Axanthic with Sable, and they are beginning to share their results. Although I haven’t seen an adult specimen yet, based on the juvenile appearance, the combination of Axanthic's black coloration and Sable’s emphasis on white creates a beautiful black-and-white harmony.

Among those studying Sable genetically, there is an ongoing debate about whether it is genetically co-dominant or incomplete dominant. I personally believe that Sable is likely incompletely dominant, but I also consider the possibility that it could be co-dominant. So, we reached out to Dr. Choi, who is a biologist at Columbia University, NY. We presented photos of Sable specimens, their characteristics, and images spanning three generations, asking for insights on how this gene could be classified. His response was that simply observing the physical characteristics and inheritance patterns of the same gene over multiple generations is not enough to definitively determine whether the dominant trait is co-dominant or incomplete dominant with 100% certainty. He mentioned that being 100% certain is only possible through genetic testing, which can only be done when there is enough data to support it. Sable is undoubtedly a fascinating morph. Not only does it enhance the beautiful white patterns that many people desire, but it also makes the base color of the morph stand out even more. We are excited to see how Sable will interact with other morphs in the future and what new characteristics it will reveal.

We will cover the results of case studies and dominant-based combinations we have conducted in the next episode.
