Key Morph Traits & Genes
Specific genes, like Eclipse, Tiger, Flame, and Harlequin, dictate notable traits in crested geckos, influencing coloration, pattern, and scale characteristics for breeders․
The Eclipse Gene
The Eclipse gene is a dominant trait in crested geckos, significantly impacting eye appearance and dorsal patterning․ Geckos possessing the Eclipse gene exhibit darkened or solid black eyes, a striking characteristic easily observed․ This gene also influences the coloration along the gecko’s back, often creating a darker, more contrasting dorsal pattern․
Interestingly, the expression of the Eclipse gene can vary in intensity․ Some geckos display a complete black eye, while others may have a slightly speckled or greyish hue․ The presence of fully darkened eyes is a strong indicator of the Eclipse gene within the gecko’s genetic makeup; Breeders utilize this gene to create visually stunning combinations and unique morphs, enhancing the diversity within the crested gecko community․
The Tiger Gene
The Tiger gene in crested geckos is responsible for bold, striped patterns resembling those of a tiger, hence the name․ This gene creates distinct, unbroken vertical stripes along the gecko’s sides, contrasting sharply with the background coloration․ The intensity and thickness of these stripes can vary considerably, depending on other genes present․
The Tiger gene is considered incomplete dominant, meaning that heterozygous individuals (carrying one copy of the gene) will display a noticeable, though often less pronounced, striped pattern compared to homozygous individuals (carrying two copies)․ Breeders often combine the Tiger gene with other pattern genes, like Harlequin, to create exceptionally complex and visually appealing morphs․ The resulting combinations showcase a remarkable range of striped and patterned designs․
The Flame Gene
The Flame gene in crested geckos introduces a striking pattern characterized by dorsal flames or chevrons running along the spine and often extending down the sides․ These markings typically contrast with the base color, creating a visually dynamic effect․ The intensity and shape of the flames can vary, ranging from subtle hints to bold, well-defined patterns․
Flame is considered an incomplete dominant gene․ Heterozygous individuals (carrying one copy) often exhibit a less pronounced flame pattern than homozygous individuals (carrying two copies)․ Combining the Flame gene with other pattern genes, such as Harlequin or Tiger, can produce incredibly intricate and unique morphs․ Breeders utilize this gene to enhance the visual complexity and aesthetic appeal of their crested geckos, resulting in highly sought-after combinations․
The Harlequin Gene
The Harlequin gene is highly prized in crested gecko breeding, creating dramatic and extensive patternation․ It’s characterized by bold, contrasting base colors dramatically interrupted by patches of a secondary color, often cream or yellow․ These patches aren’t simply spots; they’re large, irregular areas that cover a significant portion of the gecko’s body, creating a fragmented appearance․
Harlequin is an incomplete dominant gene, meaning the expression varies․ Full Harlequins display the most extensive pattern, while partial Harlequins have less coverage․ Combining Harlequin with other genes, like Flame or Tiger, yields stunning “Super Harlequin” and “Extreme Harlequin” morphs․ The gene’s impact on pattern makes Harlequin geckos exceptionally popular among collectors and breeders seeking unique and visually striking reptiles․
Complex & Combined Morphs
Combined morphs, like Super and Extreme Harlequin, and Full Pinstripe, showcase intricate genetic interactions, resulting in breathtaking and highly sought-after crested gecko appearances․
Super Harlequin
Super Harlequin crested geckos represent a striking and highly desirable morph, characterized by extensive pattern coverage․ These geckos possess a significantly higher amount of harlequin patterning than standard Harlequins, often displaying nearly complete coverage across their dorsal and lateral surfaces․ This intense patterning is achieved through the combination of two copies of the Harlequin gene․
The resulting appearance is a dramatic mosaic of contrasting colors, typically featuring bold, flame-like markings against a base color․ Super Harlequins are prized for their unique and visually captivating aesthetics, making them popular among breeders and collectors․ The expression of the Super Harlequin morph can vary, with some individuals exhibiting more refined and intricate patterns than others, influenced by other genes present in their lineage․

Breeding Considerations & Genetics
Understanding gene inheritance – recessive, dominant, and co-dominant – is crucial for predicting offspring traits and achieving desired morph combinations in crested gecko breeding․
Understanding Recessive, Dominant, and Co-Dominant Genes
Crested gecko genetics are governed by these three inheritance patterns․ Dominant genes express their trait even with only one copy; a gecko needs only one allele to display the characteristic․ Recessive genes, however, require two copies for the trait to manifest – meaning both parents must carry the gene․
Co-dominant genes are fascinating; both alleles are expressed simultaneously․ This results in a blended or combined phenotype, unlike dominant genes where one masks the other․ For example, the Eclipse gene often demonstrates co-dominance, influencing eye appearance․ Breeders utilize Punnett squares to predict probabilities, carefully selecting pairings to achieve specific morphs and avoid unwanted traits, understanding these genetic principles is vital for successful breeding․
