Answer:
A. Grandmother.
B. 0
Explanation:
A. If there is no history of the disease in the family, there were only female unaffected genetic carriers. Duchenne muscular dystrophy is a recessive disease linked to the X chromosome, all man with the mutation will display the disease, since they have only one X chromosome (XY). Women have XX, so, if they inherit an abnormal dystrophin gene, but they have a normal allele on the other X chromosome, they won´t develop the muscular dystrophy.
B. The problem does not state that the woman is a carrier, so, the probability of having a child affected is zero. The disease is linked to the X chromosome, so, sons will not be affected, and daughters would have a copy of the mutated gene, but will not display the symptoms.
