Mothers always pass the X chromosome due to how the egg works from what I remember. The sperm determines whether you get x or y for the second part.

There is a rare event where you can have multiple sex chromosomes, like XYY, but the X is always present (at least for humans). Considering the genes in an X chromosome are vital to life, even if we could artificially create YY, it would probably end up nonviable
