In human, a type of blindness called aniridia (A) and migraine headache (M) are both dominant to the normal traits. What are the chances that two AaMm people both suffering from the diseases would produce a normal child with neither trait?

1. They are dominant so the ONLY way to be "normal" for both traits is to receive all 4 recessive genes (1 copy of each from each parent)So 0.5*0.5*0.5*0.5= 6.25%
you can also think of it as the 1 in the 9:3:3:1 = 1/16
