Answer:
The correct answer would be 1/32
Explanation:
Mary and Justin can have affected child only when both of them are carriers that is, both of them should be Gg.
The probability of Justin's father to be a carrier is 2/4 or 1/2 [1 GG: 2Gg: 1gg].
Similarly, the probability of Jean to be a carrier would be 1/2.
Thus, the probability of Justin and his father to be a carrier would be equal to 1/2*1/2 ⇒ 1/4.
The probability of Mary to be a carrier = 1/2.
So, the probability of Mary and Justin to be the carrier of the disease would be 1/2*1/4 = 1/8.
Now, the probability of having an affected child would be 1/4 as it is a recessive disorder.
So, the probability of Mary and Justin to have an affected child = 1/4 * 1/8 ⇒ 1/32

Ovulation problems are often caused by polycystic ovarian syndrome (PCOS). another case is the body is just too old, and is shutting down. adoption is sometimes expensive, and has a lot of paperwork, but giving a child a family; is the best gift of all. some parents just aren't fit to take care of their child(children), so they go into foster care, and have the choice of either living on their own; or being adopted.....but in some cases, they don't have the choice, because they are too young to decide that.
