In the omegaverse, alphas are at the top due to their capability, natural leadership and better physical build. Betas are normal like humans. Omegas are physically weaker and often looked down upon, and male omegas develop a womb so they can get pregnant. Dominant means strong pheromones, recessive means weak pheromones. Pheromones are like a scent that alphas and omegas can control at will and each person has a unique scent. Alphas and omegas have periods where they have a strong urge to mate.
