उत्तर
50%
Explanation:
A haemophilic male (XhY) and a carrier lady (XXh) have a 50% of probability of conceiving a haemophiliac daughter. This is because one of the two probable daughter genes codes for haemophilia, whereas the other does not. Half of the daughters are carriers and half are hemophilic.
