Aniridia is a type of blindness that is due to a dominant gene. Migraines are the result of a different dominant gene. Suppose that a woman who is not blind, but whose parents both suffer from aniridia, goes to a genetic expert for advise. She suffers from migraines, which her father also has. She wants to know if she marries someone who has neither of these conditions what the chances are that her children will suffer from:

1. aniridia only

2. migraine only

3. both migraine and aniridia
