The Pixel trait has been heating up within the Crested Gecko group with conversations on-line, in podcasts, and naturally at reptile expos. Now we have seen lots of curiosity within the trait and sharing of analysis and dialogue to this point, which is extremely encouraging for this trait and our group of crested gecko breeders. We all know releasing our Tangerine Goals stirred the pot, and begged the query “What’s up with Pangea’s Pixels?” We all know you’re , so, right here’s our pixel story:
However first! Here’s a key that will help you perceive the doc:
- Traits are capitalized: Pixel, Tiger, Pinstripe, and so on.
- Breeding teams are italicized:Tangerine Dream, Glow Stick, Pixel 1, and so on.
How It Began
In 2018, Pangea found fascinating geckos with uncommon sample distribution in our assortment. These founding animals have been product of hyper-tangerine animals with darkish bases and have been dubbed Tangerine Dream. This venture was saved pretty quiet and small till not too long ago. Initially of this venture, we didn’t know a lot about it apart from that it was particular and we needed to be taught extra.
In 2022, we paired a Tangerine Dreammale with a Lilly White feminine. This group was known as Glow Stick because the aim was to supply hyper-tangerine Lilly Whites, which we hoped would glow! Glow Stick produced ten animals, three of which have been Lilly Whites, with a kind of three choosing up the tangerine trait. Though many non-Lilly Whites from this pair obtained the tangerine trait, the group was damaged up earlier than the 2023 season.
In 2023, two pairs of our Tangerine Dream line have been actively breeding. These two pairs have been referred to as Tangerine Dream 1 and Tangerine Dream 2. These two teams produced 24 infants for that season with 100% of the hatchling phenotypes matching the mum or dad’s foremost phenotype with minor variations in construction, shade, and quantity of sample. See extra on these pairing in our Teams part under.
What’s in a Identify
Whereas merchandising the Flora Fauna Convention in 2023, Pangea had a few of our Tangerine Dream animals to indicate to the group for dialogue. Whereas taking a look at these geckos, some breeders remarked that the animals resembled what many known as “Pixels” or “Tremendous Pixels.” At the moment, Pangea was not monitoring the Pixel trait within the pastime and took these opinions with guarded pleasure. Following that present, we have been on this trait and commenced monitoring and researching what breeders and collectors have been saying about and calling Pixel.
After evaluating the pixel assortment from our two teams to what was being known as Pixel on-line, we started to note methods to establish what we thought was the identical trait. Primarily based on our observations, most individuals working with Pixel have the identical trait as Pangea, so Pangea adopted the time period Pixel as a trait in ourTangerine Dream line.
We gained a eager eye for these patterns by way of our observations and found different breeding teams creating the identical Pixel phenotype in 2023. We now have a cause to imagine that Pixel is amongst a number of Pangea XXX and Pangea Excessive Harlequin lineages, which is supported by our inheritance idea (see Pixel Inheritance under).
Since then, Pangea has produced many Pixels and we’ve discovered a factor or two in regards to the trait.We’re excited to supply our findings, so with out additional ado, let’s start!
The best way to Perceive and Describe the Phenotype.
Pixel is a basic sample disruptor. White and orange patterns seem to disrupt or scatter resembling pixels or static. The sides of the affected sample are all the time discretely ‘pixelated’ and don’t show clean edges or traces.
Sure sample expressions and trait combos could make distinguishing the looks of the Pixel trait harder. For instance, high-coverage patterns may be too dense to supply the identical disruption all through and solely present pixelation on the edges of the sample. Moreover, sample shade is thought to fade as animals develop, and traits like Snowflake might trigger mixing, disguising the distinctness of sample disruption from the Pixel trait.
Dorsum
Figuring out the Pixel trait is most simply achieved by wanting on the dorsum. That is essentially the most constantly affected space, particularly on the dorsal ridges. The affected dorsa have disrupted patterns that may manage laterally or perpendicularly.
Pixel does permit sure typical crested gecko dorsum options to show, together with linear formation and Tiger breaks, however not all dorsal traits seem to exist when the Pixel trait is current like chevron or ‘S’ formed sample.
Pinstripe
Most Pixels in Pangea’s assortment have laterally organized patterning between the dorsal ridges. This expression is usually displayed as two thick traces with a skinny base-color stripe on the backbone. This expression resembles a “Tremendous-Stripe” with out the Pinstripe trait. This venture and dialogue haven’t been to debate Tremendous-Stripe theories, nevertheless, it’s price mentioning that this show might elevate new questions on Tremendous-Stripe.
A Pinstripe Pixel has but to be documented at Pangea as of publishing this text. Though we at Pangea haven’t seen animals displaying full Pinstripes and Pixel concurrently, we aren’t ruling out the potential of them showing collectively and plan to check this additional.
The animals we will confidently label as Pixel do not need the definitive Pinstripe traits. In our inhabitants of Pixels, dorsal crests usually are not strongly raised and arranged into a good line just like the Pinstripe trait phenotype. The distinct lack of Pinstripe structural traits in our inhabitants suggests these traitscannot coexist.
Most offspring from Glow Stick (see under) show Pinstripe. We imagine these geckos are all heterozygous for Pixel and are working to reveal this by breeding them to geckos which are visible Homozygous for Pixel. We anticipate the end result of those teams to assist inform the Pinstripe-Pixel interplay.
Laterals
A crested gecko’s laterals are the areas on their sides, between the neck and tail, not together with the limbs. On our Pixel laterals, sample shade constantly seems on the ventral ridges and close to the dorsum. Sample shade discovered on the ventral ridge in our Pixel inhabitants extends upwards, typical of Harlequin sample.
Pixel considerably impacts patterns on laterals, which may show a spread of expressions. This variation relies on the quantity of sample current, if the sample is extra laterally organized, or if there’s a vital perpendicular affect from Tiger.
Excessive protection expression can forestall sample distinction since there isn’t a separation, which makes reliably figuring out Pixel on laterals harder. Excessive protection patterns may be too dense to supply the identical disruption all through and solely present ‘pixelation’ on the edges of the sample. Sadly, this makes figuring out Pixel on laterals tough.
Tiger with Pixel
Tiger and Pixel coexist in particular person phenotypes, nevertheless, this mixture isn’t totally understood. It’s unknown if Pixel is altering solely the sample distribution of Orange Sample, White Sample, and Tiger, or one other unknown chance. Now we have seen animals with dorsal breaks and lateral patterns damaged perpendicularly, just like what Tiger does on many Excessive Harlequins. Furthering the confusion, now we have additionally noticed a mottled sample on a number of animals, like what some would name brindle. Pixel could possibly be affecting the Tigering, sample, or each.
Tail
The breeding group usually seeks “het markers” and “tail markers” hoping for an incomplete dominant trait to enhance their capacity to establish genes and enhance breeding outcomes. Now we have but to search out any tail patterns which are true in all instances. Many animals show an analogous tail sample, the place the everyday saddling of the white sample on prime and reverse-saddling of the darkish on the underside are evened right into a straight border. Nonetheless, now we have seen this sample in different animals that don’t categorical the Pixel phenotype or have any identified relation to a Pixel, which suggests it’s an unrelated trait.
Only a few animals show a related ‘Y’ as the bottom of the tail joins the dorsal ridges with a majority having a break in between the tail and dorsal sample. A majority of our adults have a connection from the dorsum sample to the tail sample.
Inconsistencies within the tail sample throughout all topics recommend Pixel doesn’t uniquely have an effect on the tail sample. The distinction between juveniles and adults is probably going on account of sample migration throughout ontogenesis. The even, straight border between tail colours on some people does elevate our curiosity, however warrants separate analysis.
Pixel Inheritance
Our observations point out the inheritance is recessive. This implies heterozygous animals show no indication of the trait and solely homozygous animals will categorical the phenotype with out necessities of different genes or traits. The inheritance idea is according to the group’s basic opinion and outcomes from our breeding initiatives. Utilizing our working description for the phenotype to establish when Pixel is current, we will extrapolate inheritance data based mostly on the outcomes of breeding these animals.
Our Tangerine Dream toTangerine Dream pairings have resulted in 100% inheritance of the principle phenotype options. Visible-to-visual pairings all the time produce a visible.See Tangerine Dream 1 and Tangerine Dream 2 under. This consistency in phenotypes and inheritance from a number of teams demonstrates that an inheritable trait determines the phenotype.
Once we paired a Tangerine Dream male with a non-pixel feminine, not one of the produced offspring exhibited the Pixel phenotype.See Glow Stickunder. By way of this, we will infer that if both of the mother and father is lacking the gene altogether, their offspring won’t present the trait. This eliminates the potential of the pixel genotype being a dominant trait or an incomplete dominant trait due to the identified heterozygosity and lack of any Pixel-related phenotypic variations between the offspring.
As beforehand talked about, we found breeding teams producing phenotypes that matched our description with out the mother and father expressing the identical phenotype. Which means non-visuals to non-visuals can produce visible Pixels. For this to occur every mum or dad should have had one copy (heterozygous) of the gene that every contributed, ensuing within the offspring having two copies of the gene (homozygous).
Lastly, a more moderen Pixel venture offspring demonstrates the recessive inheritance idea. A male from ourTangerine Dreamline was paired with a feminine from our Glowstickline. The male is homozygous for Pixel and the feminine is heterozygous for Pixel. This pair produced a number of hatchlings displaying the Hyper Tangerine and the Pixel phenotype.See Pixel 1 under for particulars. This end result confirms the mode of inheritance to be recessive by offspring, with one visible mum or dad and one visible grandparent on the other aspect, displaying the Pixel phenotype.
The Way forward for Pangea Pixel Tasks
Now we have produced many animals that show the Pixel phenotype from a number of lineages, although we nonetheless query the way it interacts with different traits. To assist us perceive the trait, enhance upon our objectives, and improve heterozygosity, now we have dismantled our Tangerine Dream pairs in alternate for brand spanking new pairs.
At the moment, now we have a number of pairs put collectively for our Pixel venture. All our pairs include one confirmed Pixel and one gecko as a testing variable. Our testing geckos embody suspected Pixels, non-visual mother and father of Pixels (presumed heterozygous), and non-visual offspring of Pixels (heterozygous). Pairs have been chosen as an alternative of teams to reveal the lineage of every animal with full accuracy.
Now we have a number of objectives for these pairs. These objectives embody creating extra outcrosses to broaden the Pixel gene pool and enhance heterozygosity, testing the mode of inheritance, enhancing crest and head construction, combining Pixel with new traits, and making extra Pixels!
The Pixel trait presents unimaginable prospects by combining it with different traits for gorgeous combos.

Teams
These are previous and current Pangea Pixel teams referenced above. This part affords additional data and specificity for these breeding initiatives.
Tangerine Dream 1
Tangerine Dream 1 (TD1) was a pair with the female and male displaying Pixel and Tangerine. Every animal has an almost strong dorsal sample. The male shows an Excessive Harlequin Sample and Tigering. The feminine has a smooth mottled Harlequin sample. 100% of the Tangerine Dream 1 offspring show Pixel and Tangerine.
Tangerine Dream 2
Tangerine Dream 2 was a trio consisting of 1 male and two females, every displaying the Pixel phenotype and Hyper Tangerine. The male from this group has a mottled look all through his physique. Each females from this group have much less dorsal protection and extra damaged patterns than their Tangerine Dream 1 counterparts.
This group produced 9 offspring, every displaying the Pixel Phenotype and Hyper Tangerine. This group of offspring shows mottled/brindled patterns and dorsal breaks whereas holding according to the Pixel phenotype.
This close-up of thedorsa from Tangerine Dream 2 mother and father and offspring exemplifies the sample disruption of the Pixel trait with out the affect of excessive protection or strong dorsal sample. Dad and mom are featured on the prime with offspring under.
Glow Stick
Glowstick consisted of a high-coverage Lily White male and a Tangerine Dream feminine. The Tangerine Dream feminine is homozygous for Pixel and presumably homozygous for Tangerine (aka Hyper Tangerine). The desaturation of shade sample with age makes figuring out how prevalent the Tangerine trait is with this particular person tough. All Glowstick offspring phenotypes show Tangerine which infers the dam is homozygous for Tangerine.
Of the ten offspring from Glow Stick, all show the Tangerine trait, three show the Lilly White trait, and none exhibit the Pixel phenotype.
Pixel 1
Pixel 1 is the end result of our Pixel venture bringing collectively one among our favourite males, the previous sire to Tangerine Dream 2 with a Lily White feminine from Glowstick. The male shows the Pixel phenotype Hyper Tangerine and has a mottled look all through his physique. The feminine is a Tangerine Lilly White and is heterozygous for Pixel. This mixture of traits has eight attainable outcomes seen within the combos under.
So far, this group has produced seven hatchlings. Of the primary seven offspring from Pixel 1,two show the Pixel phenotype, two don’t show the Pixel phenotype, and three show the Lilly White trait and presumably Pixel. Confirming the Pixel trait with the Lilly White geckos is tough as a result of it’s not well-known how the 2 traits will work together at their younger age. Some group members recommend it takes a couple of months for this interplay to change into obvious.
