Answer:
The correct option is A) XY and XX
Explanation:
As the pedigree shows, the males and female parent do not have any disease nor are they carriers for any disease. Hence, they will have a normal genotype. The slash on the members of the pedigree show that the individual is dead. But for the first two parents, neither the sign for a disease nor for carrying a disease is shown. Hence, they will be normal.
