Ok this is what I ended up doing chance of father being carrier 2/3. Chance of mother being carrier 1/100
2/3*1/100= .00666
Then I multiplied the chance that if both parents are carriers that the recessive gene will be the one carried on (1/4)
So .00666 * (1/4)= .00166 or 1/600
Can OP confirm what the right answer is?

drangel you know father is 2/3 because you know for sure he does not have the disease. In this case that it's a recessive gene that knocks out the possibility completely of the father being aa. Meaning the father could only be AA, Aa, or aA. So the probability of him being a carrier is 2/3

The correct answer is C. The risk that the husband is a carrier is 2/3, and the risk that his wife is a carrier is 1/100. If they are both carriers, the risk to a child is 1/4. The overall risk to a child is therefore (2/3) (1/100) (1/4) = 1/600.
