G6PD is an X-linked condition, so males cannot be "carriers" - they can have the disease but they can't pass it on unless they themselves have the disease. More regularly, the mother is the "carrier" and since boys only have one X chromosome, it is more likely that her sons will be affected rather than her daughters.
