Don't know where I've read it but I think in their world, beast people are all male and alphas . It made sense to me as well cuz the entire series, there's not a single female beast or omega beast. That's why a lot of aristocrat family are running out of heir and keeping a harem of omega cuz beast people are automatically an alpha. Basically, think of it as it only male are being born and world is running out of female? How are they gonna sustain the world population without female? And if female beast people really do exists in their world, they'll be the utmost priority to be the spouse of aristocrat beasts cuz they'll have the purest blood and shit, not being sired from human and a beast. Seeing how toneria act with all the pure blood shit.
