It's a mistranslation, her mom is an Alpha. Didn't she said that her son is a unique case of a Dominant Omega because he can't sense Alpha pheromones despite having someone (an alpha) being near him (in this case, she meant the alpha as herself.) I don't know why the official trans have a lot of mistakes.
If his omega father birth him, is his omega mother the other biological parent? If so, omega x omega = baby? Does Alpha female even have the p to do the deed? In other series, they do. Then what is the point of being female and male? Determining physical strength? @.@ con-fus-ing!
