The chance of a male offspring inheriting the same disease is 100%

Explanation:

Those Y-linked diseases are present in the genes present in the 'Y - chromosome'. For the female offspring, it inherits the X chromosome from male and X-chromosome from the female whereas for being a male offspring it requires Y chromosome from male, through which the disease will also be transformed and a X chromosome from the female parent. So it is proved that only the male offspring have the tendency to inherit the same disease and the chances of the disease in female is nil.
