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!

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
