Answer:
25 percent
Step-by-step explanation:
The reason why it is is because of how when you draw the punnet square, you have to write B in the first top part, and b in the second top part. Then, you draw B in the top left corner side, and then b in the lower left corner. When you write the Bb's, BB, and bb, you get a 25% chance that the baby would have blue eyes.
Hope it makes sense!
