Okay... yeah XX stands for female... and XY stands for male... the easiest way to remember that is that the man decides the sex of the baby... therefor he has to have 2 different variables
anyways... another question similar to the one asked first... are ayu and her mother on speaking terms? Whats her relationship to her? What happened... I have been a ayu fan for a long time, but I never understood about ayu's mother...
