Who do females get sex linked traits from?
Men normally have an X and a Y combination of sex chromosomes, while women have two X’s. Since only men inherit Y chromosomes, they are the only ones to inherit Y-linked traits. Men and women can get the X-linked ones since both inherit X chromosomes.
How are sex traits inherited?
