Answer:
Hemophilia is a sex-linked recessive disorder in which a person's blood do not clots and he can bleed to death even after minor injuries because blood will keep running due to a small cut.

Question: What will be their children’s possible phenotypes?
If a woman who is a carrier for hemophilia marries a hemophiliac man, their genotypes can be denotes as :
Here H, indicate normal gene and small h indicate defected (hemophilia) gene.
Parents: XHXh X XhY
Offspring: XHXh : XHY: XhXh: XhY
Phenotype of offspring:
XHXh: The child will be daughter and normal (25 % chances)
XHY: The child will be son and normal (25 % chances)
XhXh: The child will be girl and Hemophiliac (25 % chances)
XhY: The child will be son and Hemophiliac (25 % chances)
