Pangea is proud to be hosting these fascinating geckos produced by Tom Favazza of Geckological. Tom has brought us some of his amazing Cold Fusion line crosses that we are excited to have available for you. Read what about what Tom has to say about these geckos:

The Cold Fusion line has more than just that signature bluish tone base color. It appears to be a single enhancer trait at this time, but maybe a combination of traits, that present in a distinct manner.


A reduction of melanin and yellow in black-based animals causes light to refract, in a particular way, giving them the bluish hue. Being inc-dom gives a wide range of firing in this line. As the dominance of the black base increases, the firing becomes darker and the Cold Fusion trait is less noticeable, but it becomes more apparent as these animals fire down. The trait can make these higher melanin animals appear cool grey or a really dense black, especially when phantom is present. There are also examples of animals that stay a much lighter bluish tone that is being worked with now. These are the most striking and sought-after animals in this line. They have been outcrossed to keep heterozygosity up, keeping the line strong, so it can continue to be developed properly.


Red-based animals regularly show more of the bluish tone, when they fire down, rather than the dull grey or brown commonly seen with reds. Some of the next-generation red phantom Cold Fusion animals appear to have an even-toned dark cherry appearance when fired up. Phantom, being a melanin contributor, brings in a darker look and can sometimes have a slight yellow glow, from the brown/yellow melanin, that shows during different phases of firing. With Cold Fusion, being incomplete-dominant, it is an expected interaction and helps support evidence of its inccomplete-dominant nature.
Yellow and orange Cold Fusion variants are quite stunning, having the bright white pattern, which is another attribute, being a part of or being developed along with Cold Fusion. This bright white pattern, along with clean yellows, has led to the consideration of Cold Fusion being a hypo/ghost trait. When we compare across species, it behaves similar to Desert Ghost and Super Cinnamon ghost in ball pythons. When the yellow/orange variants are bred, back to the traditional Cold Fusion animals, the phenotypes are the bluish-toned Cold Fusions and the hypo yellow/orange variant Cold Fusions, but they never act inc-dom with one another and blend.
Non-Cold Fusion yellow animals always have a white/cream pattern, rather than orange, but Cold Fusion line yellow/orange based animals always have a pure white pattern. On the bluish Cold Fusion animals, the orange pattern can be present but is typically more muted and the white remains the same as the pure white pattern we see on the yellow/orange variant Cold Fusion animals.


On specific darker-based outcrossings, I am seeing the orange pattern losing the color and only showing the brown/yellow melanin where the orange pattern should be.
An additional trait has also emerged within this line. It is a soft type of scalation that we refer to as SAF. This structural development often adds an overall matte or smooth finish to the geckos when present.
The Cold Fusion trait has been taken in many directions and produces distinct phenotypes that stand out in comparison to non-Cold Fusion animals of the same phenotypes. These directions are being pursued to gain more knowledge of this line and the genetics of crested geckos in general. In order to continue following this endeavor, it is time to release some of these animals, into the hobby, to see how it enhances and is affected by other traits.
