Alpha- (male and female) dominant who can create bonds with omegas (fated pairs, soul mates, or whatnot) males are usually superior species followed by female alphas (have both female and male genitalia).
omegas- (male and female) umm inferior species. male omegas can also give birth. alpha x omega pairs of the same s** can have children.
betas are just common folks... they are just vibing in society.
