Marbling - (Pattern/Color)
Trait Details:
Genotype: M
Phenotype: Appears dominant (more pairings are still needed)
Allelism: None known
History of Marbling
Marbling is still in the early stages, a few generations have been produced and the project stems from a single animal, “Alpha”. Alpha started to produce animals with unique coloration and patterning which was noticed by Yunju Lee. Alpha produced offspring with dark colored scales, some areas appear somewhat translucent, and there is a strong effect to the patterning that looks similar to the Marbling found in high-quality wagyu steak, which is where the name stems from. The patterning produces mottled bands and orbs of concentrated solid patterning, instead of soft snowflake patterning. The Lilly White animals also have reduced patterning and darker overall coloration. Another characteristic noticed is the belly coloration is darker than usual and the base has a reddish wine color to it. In the Lilly White combo the belly coloration produced by the Lilly White gene is also reduced in patterning. The unusual characteristics in the offspring are what prompted Yoon to try and test if it could be a unique gene that was producing the phenotype. Marbling has been paired with several females and Alpha continues to produce the Marbling phenotype. This result makes it less likely to be a recessive mutation. Alpha does not display the Marble phenotype and instead looks like a typical Lilly White. We can speculate on a few causes for this such as epistasis, chimerism, and a few other genetic anomalies. However, more test breeding is needed to further understand why this is the case with Alpha. The offspring do seem to pass on the trait dominantly and so does Alpha. Although no clear super form has been proven, Yoon does suspect a few offspring to be homozygous for the gene due to them expressing the phenotype more strongly. These offspring have been selected to breed to test the hypothesis. Additionally, this and other pairings will also be done to test to see if stacking or a morph combo is in any way a result of what is producing the phenotype instead of a new gene.
Phenotype Overlap
Marbling has several characteristics in common with other notable morphs that seem to produce similar results or display a phenotype overlap. The morphs Marbling will be tested against are Pixel, Plague, Shatter, and XXX. Although similarities have been noticed there are several distinct differences in the Marbling morph that are not prevalent in the others. Marbling shares similar characteristics with how the pattern is broken into smaller localized regions. However, it also produces streaks in the pattern that is different from what we see in the other morphs. The breaks and freckling in the pattern that forms are similar to what we see in the Pixel and Plague morphs so there is overlap in these. We also see there is a similarity to the Shatter morph with regards to the pattern forming in different directions, but Shatter lacks many of the unique characteristics found in Marbling such as the dark scales and orbs of solid pattern. These are the many characteristics found in Marbling that we will be extensively testing against to make sure it is a unique trait. Along with genetic inheritance, breeders will be testing allelism to known traits and combo morphs. Below are several offspring that display the unique characteristics previously mentioned.
Another distinct characteristic found in Marbling animals, that is not found in other morphs, are dark scales that are found throughout the animal. The dark patterning found along the dorsal, even in Lilly animals, seems unusual and is distinct from Phantom LW combos and the Margin characteristic found in monstly Yellow base Phantoms. The dark scales stand out more in the Lilly White combo. The belly of the Lilly/Marbling has a distinct dark freckling that is not commonly found in Lilly White. Although there are several characteristic overlaps with various combos none are found together in any one morph except Marbling. This, with how it passes from Alpha to offspring is why Marbling presents with its own distinct characteristics and seems to be behaving like a trait. If it were a combo we should see more self segration of those individual traits that we are not seeing in the offspring, even with outcrossing Alpha to several unrelated females. Below are close-ups of the dark scalation found in one of the LW animals, the non-Lilly White offspring, and the bellies of those animals.
Moph Description
The Marble morph has broken pattern that resembles Marbling in high-quality Wagyu steak. The pattern and formation of the pattern is unique with how it presents in the Marbling and Marbling/Lilly White combo. Along with the unique marbled patterning the base coloration is also affected, producing a wine-colored base with an almost translucent appearance to it. The patterning forms in orbs and streaks of solid white coloration. Although there are patches of dark coloration the dorsal and head region display it the strongest. Upon close inspections, you will notice black-tipped scales freckled throughout and can also form patches of dark pattering that resemble scorch marks along the neck, head, dorsal, and body, similar in appearance to margin but dispersed throughout. The morph is most distinct as a Lily White due to the contrast produced by the combo. Below is a family tree of what has been bred and produced. Additional 2025 pairings are not currently shown.
