In this case, the mother was a carrier of hemophilia and she transfers that mutant allele to her daughter and as the daughter did not get any sex chromosome from her father.
Therefore, mutant X expresses itself and she is hemophilic.
This X did not express in case, of her mother due to fact that it is a recessive allele and only expresses when both genes is the same state.
