okay so i should be alseep rn but i was thinking in ddvau, or desert duo vigalantie au[alternate universe] jimmy and grian are cousins, but by my understanding both avians, therefore they would both have to have a parent gene from a grandparent that was passed down to both of their parents and in tern to them unless it was pure coincidence.
but lets say that it wasent just coincidence that jimmy is a canary hybrid [avian], by my understanding and grian an avian as well. if so they would both have to have a parent gene passed down to both of them, also known as a dominat gene. if it was a dominet gene that passed down a physical characteristic it would be autosomal dominant. - autosomal dominant: where the gene for a trait or condition is dominant and is on a non-sex chromosome. 1.a autosomal dominant is a pattern that characterisitcs are inherited. if i understand correctly, which i probably dont, both parents would have to carry the gene for the hybrid to be born if both parents didnt have that trait, e.i wings. thats called autosomal recessive.
[ next day, 17/1/2024: i wake up and come back to this holy shit yall, what the hell is going on okay thats very sience, anyways back to the essay. ]
heres a diagram i fould that explains it quite well:
to the next part bird species, jimmy, if im correct is a canary whereas grian isnt an actual bird species, but to make things simpler i decided to look up bird species that matched how he appeared, the colours of his wings ect. I found three birds that matched, or matched as well as possible, the pink-browed rosefinch, the Pine grosbeak and the pink headed warbler.
the pink headed warbler's feather pattern fits grians wings in the way of colouration from pink to black at the primary and secondary feathers, but, the bird itself, though stated to be pink is more of a red colour, whereas the pink-browned rosefinch and the pine grosbeak colours are more accurate except for the black part. but lets say that this ficticious bird fits under these three, looking at them, especially the pink headed warbler, seems to be a passeri, also known as oscines, or commonly songbirds. heres where we come back to jimmy. a canary is a songbird. 16% of all wild birds have been known to crossbreed with eachother, and that number goes up to 22% if you include birds in captivity. birds in the wild dont mate like humans do, humans get to know eachother, go on dates, and take long times before deciding to have offspring. whereas birds on the other hand, have mating periods, where the males try and mate with as many females as possible. avians, or bird hybrids, the ones crossed with humans, are more human and wild bird. this means that dating is more of an option, im not trying to make this weird but we have to talk about this to get the point across. to have the genetic move from grandparent to both parents to their children and for the gene to mutate to have two differnt bird species come out of that, having them under the same suborder: songbird, makes more logical sense, though with jimmy having the smaller wings i would assume that the gene would have been worn out, reduced or overpowered by others, still giving him the feature yet having it be minimal. whereas grian has much larger wings and even has mutated to have such wings on his head. i believe its safe to make the assumption that the grandparent in question that this hybrid gene sprung from had larger wings like grian. though breeding the change in wing types, probably crossbreeding of other bird speices led to the fictional bird that grian himself is, whereas jimmy would be a human/avian parental group, grian is more likely to have an avian/avian parental group to change his genetic material into having those types of wings.
perhaps one of said avian parents is one of the other birds mentioned [ see images above ], most likely a pink headed warbler, not only wearing down the yellow [if grandparent was a canary, it does make the most sense though to me at least,] and red colouration to make it a pink but also keeping the black-ish colour and the wings large, perhaps even mutating the gene to give grian the two sets of head wings he has in his cuteguy persona. ddvau is an amazing au created by @kitsuneisi and @xmaruu11! go check out the master list here! i dont know why i did this but i apparently deep dived into this, sorry lol.
