The only stories I have read is mostly betas turning into omegas bc they've been bitched but if omegaverse omega's logic is that they are intersex then it means a fetus is omega at first (like a fetus would have a coding of a womb before they are even assigned which primary gender they are)
So I guess with this logic (?) an alpha and a beta that has a significantly large percentage of passive omega gene can
Be bitched.
This is why omegaverse is a fun verse to explore, it can literally change depending on the artist.aside from the basic principles, some stories have more fantasy esque take, like all the people regardless of gender can be pregnant (kashikomarimashita my destiny) or they can change an alpha to omega via drugs, or one look is all it takes to change a beta to omega (kiss me liar). Theres also where verseworld where all dominant alphas have puple eyes and changes to gold when in rut or using pheromones or something (zig stories). Or using special fruit to induce pregnancy on an alpha (smyrna and capri). Theres even one that takes a realistically take on it focusing on the societal and political side of it (takatora kun to omegatachi)
That's also what I actually have in mind, because if by this logic we think alphas have superior genes and sperm, especially dominant alphas. If they continuously knot an alpha with 5% passive omega gene and subject the bitched alpha into enough stress to trigger DNA restructuring it might be possible + the effect of pheromones too. I think 9 months would also be fine right since the bitched alpha is restructuring his organs and building a womb inside I think he'll be subjected to bitching by a dominant alphas for 9 months is my theory

i was thinking like this is pretty obvious but i just realised that in omegaverse since its like alpha x omega would alpha x alpha or omega x omega be like their minority and be considered like their "lgbtq" community, i would like to see their own pride month and all, does this make sense? im new to this lmao ALSO would someone be inclined to change their secondary gender??? wtf this is lwk fun to think abt
