Answer:

The correct answer would be b) 25 percent.

In females, X-linked recessive disorder is expressed only when the mutated gene is present in both the X chromosomes whereas in males presence of only one copy of mutated gene is sufficient to cause the disease as they have only one X chromosome.

Now the given cross will results in the production of:

  • Two daughters- one is homozygous dominant (X^{B}X^{B}) and other is heterozygous dominant X^{B}X^{b}
  • Two sons- one carries dominant gene (X^{B}Y) and other carries recessive or mutated gene (X^{b}Y).

From the test, it is clear that only one son out of 4 offspring carries the disease.

Hence, the probability will come out to be 1/4 = 0.25 or 25 percent.
