Females are carriers, males are affected.
In her case a male baby will have no risk/or the same risk as general population. Female will be carrier 33% risk I guess. I never understand this. I know I am wrong  . Someone correct me plz.

X1Y XX
offsprings: X1X, X1X,XY and XY chance of carrier : 50% chance of female carrier : 100% chance of disease ( also in males) : same as gen population

X1X XY
offsprings: X1X, X1Y, XX and XY disease probability/ carrier probability: 25% male disease chance: 50%

The chance that the baby will be SICK or HAVE THE DISEASE is 0 or the same as general population. Now the female baby is carrier for sure, but not sick. The male baby is healthy. The chance that the baby is a carrier is 50%.
