Question

according to the figure below, what is the approximate probability that a human offspring will be female? (1 point) 10% 25% 50% 75%

Explanation:

Step1: Count total outcomes

The Punnett square has 4 cells (XX, XX, XY, XY), so total outcomes = 4.

Step2: Count female outcomes

Female is XX, so number of female outcomes = 2.

Step3: Calculate probability

Probability = $\frac{\text{Number of female outcomes}}{\text{Total outcomes}}$ = $\frac{2}{4}$ = 0.5 or 50%.

Answer:

50% (corresponding to the option with 50%)
