Humanity is based on of three different sexes, which are: alpha, beta, and omega. It is not possible to know a person's gender externally from zher body, but certain gender-related stereotypes regarding clothing, for example, can give an indication of where a person belongs. Only the experienced pregnancy is physically seen in the person as enlarged mammary glands and a wider pelvis.

Studies show that the occurrence of sex is very genetic, which means that certain sexes can occur in large numbers within one family. As a result, alpha-weighted families, for example, have sought to marry their children to keep the presence of alpha within desired limits. In short, the more diverse the sexes in the family, the more uncertain the sex of the future child. However, nature is full of surprises, as genetic defects or even genes from more than one grandparent can also be activated, resulting in a child with an unexpected sex in families that are considered "clean".

Since the 1980s, parents have been able to take a sample of amniotic fluid to find out their child's gender. With the proliferation of research, abortion in omega has increased significantly. Even with conservative estimates, the chance of an abortion for an omega fetus is 30-50%, and in some Asian countries, an omega fetus has an almost 100% chance of having an abortion. As a result, screening has been made chargeable in many countries to prevent the omega population from collapsing completely. As a result, omega is found in many countries, mainly in the poorest families, who have not been able to afford a genealogy survey. Globally, omega babies are abandoned in large numbers after childbirth and most of them grow up in orphanages, from where they most often end up in the world of drugs and prostitution.
