c 75
d 50
e 25

Explanation:

Step1: Count total offspring

The Punnett Square has 4 cells (offspring): XX, XY, XX, XY. So total = 4.

Step2: Count female offspring (XX)

Female genotype is XX. From the square, XX appears 2 times.

Step3: Calculate percentage

Percentage = $\frac{\text{Number of female offspring}}{\text{Total offspring}} \times 100 = \frac{2}{4} \times 100 = 50\%$.

Answer:

d. 50
