1. The probability that a male child born to a genetically normal male and a woman who is a carrier for hemophilia will be a hemophiliac is _______?


2. A male who has an X-linked allele will pass it on to:
A) all daughters B) all sons C) 50% of sons D) 50% of daughters E) all children

I think that the answer is A. all daughters, but I don't know how to do the punnett square for this question. I tried doing it but I am not sure if I did the punnet square for this one correct but it I made it like this:

   X         Y

x   Xx         xY

x   Xy         xY


Can you guys please help me figure these problems out?

Thanks in advance!
