Answer to q. 1

ANSWER: All females normal but 1/2 of them would be carriers; 1/2 of the males would have
hemophilia, the other 1/2 normal.

Answer to q. 2

ANSWER: Yes, the daughter would have to inherit the recessive trait from both parents and since the
husband is normal and has only one X to give, the daughter could not have gotten the
recessive allele from him.
