The encoded protein is believed to be an integral membrane protein involved in small molecule transport, specifically tyrosine, which is a precursor to melanin synthesis. It is involved in mammalian pigmentation, where it may control skin color variation and act as a determinant of brown or blue eye color. Mutations in this gene result in type 2 oculocutaneous albinism.

agouti wild type and pink-eyed dilute, nonagouti castaneus (eye color variants), nonagouti unstable wild type revertant (left and right - fully wild type looking and mosaic) and unstable (middle)
is there no difference in the phenotype at all between genetically solid and tabby oranges? i thought the ones who are genetically solid have darker faces or something?
Yeah. They say the best (but still not foolproof) method to differentiate between tabby and solid reds is to look at their chins: it's white for tabbies and red for solids.
I was trying to keep everything as simple as possible, so I left this part out of the previous post. All tabbies have white chins and it always disappears with the solid allele, so on this specific area it probably reverts back the cells to produce the same pigments as all the others (while normally there isn't any pigment production here). And that's possible with phaeomelanin too, i guess.
well i've made the first draft of how the wing color genetics might work andd..
honestly i'm not too pleased with them, the only ones i really like are the top row
man i really need to find some good sources for some parrot genetics..
i do have a rough idea of what i want to do with the wing colors
basically [idk how realistic this is but there's magic in this world so wtv] the genetics of the wings are somewhat separated from the rest of the bodies of this species [still don't have a name for them ;-;] and altho their animal and humanoid forms still share some genes, the wings are almost entirely separate
well, not mitochondria kinda separate, just in different chromosomes that carry only the genetic information of the wings...
I really need to do a basic biology chart don't I.. that's probably gonna be in my next post
I think I might add budgie and/or some other parrot color genetics to the project cause 1, I'm already planning for them to have wings and 2, I like the colors :3
💬 0 🔁 1 ❤️ 1 · Post by @art-undecided · 1 image · how tf do I combine the cat E locus with the dog E locus in a way that makes sense..
I'
I have decided that since I've already made the E locus to be like the dog one.. I've moved the cat E locus into the O locus!
I just got rid of russet cause I have no energy for that one..
so starting from the most dominant:
Oc the carnelian gene, homozygous fully replaces eumelanin with phaomelanin while also making the pigment richer and deeper than usual, heterozygous with O it still replaces all eumelanin with phaomelanin but it only partially makes the fur that deep rich red, heterozygous with o it replaces eumelanin only partially with that deep rich red
O when homozygous replaces eumelanin fully with phaomelanin, when heterozygous with o it only replaces the eumelanin only partially in a brindle or patchy pattern
o is the wildtype allele, it leaves eumelanin alone
oa is reccessive to all the other alleles, it is the amber gene, and it replaces eumelanin with phaomelanin with age, but it leaves the tabby or brindle pattern alone if it's surrounded by eumelanin as you can see on the chart
this chart:

this time it's epistatic red! the O locus that cats have!
I'm prett
is still valid, just it only includes the o and O alleles
another chart for my fantasy race genetics project :D
this time it's epistatic red! the O locus that cats have!
I'm pretty sure it's not how it works in irl cats, but here it replaces eumelanin instead of simply erasing it
o is the non-red allele while O is the red allele
they are codominant :3
and I luv them
I especially love how they interact with all the other phenotypes.. the reverse tortie tabbies.. and what I will now call "double brindles", aka: brindle torties, jeez those are some pretty colors.. especially since torties will interact the same with white spotting, the bigger splotches of red and non-red with the brindle, will be beautiful
also Ur will appear over all the red, including Kb:Kb O:O :3
and also a note
on the emln patches on o:o members of this species do not show the tabby and brindle patterns, not clearly at least, they are "ghost tabbies" basically only visible in certain lighting while in O:O members or O:o only on the red patches the tabby and brindle patterns always show, even if faintly, like in cats
I am making an original species/race of beings that have an "animal" and "humanoid" form thanks to magic but also biology and I am figuring out their genetics for fun :D
I am basing those genetics off of mainly dogs, cats and horses but may add some more
I'm gonna make a video explaining everything in detail, but for now..
[btw x here stands for "any allele recessive to the other or the same allele" and I use : instead of / or nothing because it just looks better, and you can see all the dominance orders on the chart, also the colors underneath the hairs are basically just for me to help, besides Max Emln, Emln and Phmln cause those you can actually differanciate on the charts]
first with the K locus: works like in dogs, Kb is dominant black, Kbr is brindle which can separate into Kb and ky and ky is the agouti light switch gene
Kt is similar to Kbr, it is also a combination of Kb and ky but it is stable
and dominant
as well as being more uniformly patterned, it's the tabby light switch gene :D
as you can see I did the thing with Kbr being co-dom [pretty sure that's right] with Kb and ky
Kb, Kt and Kbr make the fur have no shading at all in their black patches, basically turning off the augoti there, I based it off the fact that in cats, ghost tabbies exist, even when having an a:a genotype the tabby pattern can faintly show, I took that to mean that those hairs in the pattern are fully black while the others are slightly shaded
you can see the difference on the chart between the shaded Emln hairs and Max Emln hairs
secondly the A - Agouti locus: okay this is a big one aight lessgo with the explanation, you can see the basic effect of it in the Kb:x E:x column
Ay, Ag the yellow and golden alleles, they do not have true agouti hairs, instead they have sable hairs, "tipped" hairs, these two alleles are ripped straight from dogs, do the same things as those
A the agouti allele, mix of the dog and cat A allele, true agouti hairs, "wolf sable" and normal cat agouti pattern basically look the same so that's that, whether looks more cat or dog like that's unknown polygenes that I ain't fucking with tbh
ap yk that charcoal tabby cat gene? yea that's this one basically, but this version has both agouti and sable hairs for funsies
as, ab dog saddle and "black back" [what idiot named it that..] pattern genes, nothing more nothing less, both emln and phmln hairs, no sable or agouti hairs afaik, at least in the basic version
a cats have it, dogs have it, hell, horses have it, it's our favoriteee, the full black gene, causes only emln hairs to be present [unless extension does shit...]
2nd to last Ur: the simple urajiro gene that causes lightening of the phaomelanin parts of the fur on the bottom in a point pattern, comes from shiba inus, nobody's sure how it actually works irl, so I just made it a simple dominant gene
last but definitely not least [kinda my fave now] the E locus: it mostly says where the eumelanin can go
Ep the point gene which I came up with myself, I wanted this species to be able to have similar patterns to horses but noticed none of the genes actually allow for a similar pattern to dun and/or bay so here we are, it lets eumelanin to only be on the extremities, overriding even Kb, Kt and Kbr as you can see
Em works exactly like in dogs, giving them an eumelanin "mask" over the face
E works like in dogs and horses, basically just, no fuckery happens
Ed ah domino.. combined the two different domino genes bc of laziness, anyways, it pushes back the patterns made by agouti, introducing more phaomelanin, as well as doing something.... very funky with Kt and Kbr, basically inverting them, now they appear on the eumelanin parts of the coat instead of the phaomelanin parts, because it just inverts it basically, now the patterns are erasing eumelanin instead of adding it [I understood that it worked like that from the video I watches, and I think it is very neat so I kept it]
Eh the canadian cocker sable allele, it does what Ed does but.. way fkn more [that's how I understood it] almost making it an actual grizzle, it makes fun of a by completely destroying it's phenotype basically lmao
e the recessive red gene, it erases all eumelanin from the hair, not even whiskers are left with it
phew.. that's all for today
follow me if you're interested in seeing the future updates of this project!
