Answer:
Option A
Explanation:
The father’s genotype would be XY’
Where Y’ represents the disease affected male chromosome.
Let the mothers genotype be “XX”
If the Y-linked disease affected male is crossed with a healthy female, the following offsrpings will be produced
X Y’
X XX XY’
X XX XY’
Thus, total two male offspring’s are produced and both the male offsprings have affected Y’ chromosome . Thus , in case where a disease is Y-linked all the male offsprings produced would be disease affected.
