Tom's father has hemophilia, but Tom does not have the disease. What are the chances that Tom's children will have hemophilia?
 
  a. Tom's sons will almost certainly have it because Tom will have inherited the recessive gene from this father.
  b. Tom's daughters may be carriers, but his sons will not have the gene.
 c. All of Tom's children will be carriers, but it will not be expressed until they have children.
 d. None of Tom's children will be carriers or have the illness because his X gene came from his mother, who is not a carrier.
